How often is there a lunar eclipse?
There are between 1 and 4 lunar eclipses per year.
Between the years 1901 and 2000, the average was 2.29 of them each year.
Is it safe to view a lunar eclipse through a telescope?
You do not need a telescope to view the moon. In fact many astronomers who own telescopes prefer a good set of binoculars on a simple tripod to a mounted telescope. You also do not need a lot of magnification. The greater the magnification the greater the need for a tripod as the magnification exaggerates the shaking. The moon is quite bright so you do not need the large, light gathering apertures often found in telescopes. In Fact, those who use such telescopes for Lunar viewing often must attenuate the light source with neutral density filters. To try to view the moon without them is frustrating. Any reasonably good binoculars in the 7 x 50 range will give you 7 times magnification, and the 50mm lenses admit enough light to serve the purpose. It they are "wide field" binoculars, that is even better. The duration of the eclipse is several hours and for that reason, even holding a set of binoculars can be tiring. Some sort of device like a tripod will help prevent getting tired arms. You do not need a telescope to view the moon.

When will the next total lunar eclipse happen?
The next total lunar eclipse is expected to occur on May 16-17, 2022. This will be a partial lunar eclipse that will be visible from parts of North and South America, East Asia, Australia, and the Pacific region.
What time is the lunar eclipse?
On Wednesday evening, February 20th, the full Moon over Europe and the Americas will turn a delightful shade of red because there will be a total lunar eclipse.
The timings may be obtained from the link I will place below.
What do solar and lunar eclipses have in common?
They both block light from falling on something else. In the case of the solar eclipse, the Moon blocks the Sun's light from falling on the Earth; in the case of the lunar eclipse, the Earth blocks the Sun's light from falling on the Moon.
Does a lunar eclipse happen at daytime or nighttime?
All lunar eclipses are visible only at night. That's because a lunar eclipse happens when the Earth's shadow falls on the Moon, and only people on the night-side of Earth can see the Moon at that time.
Lunar eclipses occur when the moon passes into the Earths shadow. So just as a solar eclipse occurs when you get the Sun, moon and Earth lined up (in that order), a lunar eclipse occurs when you get them lined up in the order Sun, Earth, moon.
When the earth sun and moon comes in a straight line earth in the middle the lunar eclipse occurs.
A lunar eclipse can only happen during a FULL MOON.
It can only occur when the earth moon and sun are all lined up, with the earths shadow being cast on the moon (earth between the sun and moon). Even then it's not guaranteed, as the alignment has to be perfect. The orbits at not perfect circles and on the same plane so this is quite rare. A lunar eclipse will happen with a new moon.
It occurs when the Earth is directly between the Sun and Moon. It must be a full moon when it happens. To see a full lunar eclipse, ou must be in the umbra. If you're in the penumbra, you wouldn't see the whole eclipse but most of it. ~ha.
Do lunar eclipses occur every 3 years?
Typically, lunar eclipses occur once or twice a year.
Because more than half of all lunar eclipses are partial, and because lunar eclipses are visible only from the side of the Earth where the Moon is up, you would generally be able to see a total lunar eclipse every other year or every 3rd year from your location. The rest of the eclipses would be either partial, or not visible from your location.
You can check the NASA Eclipse Web Page to see the catalog of all eclipses from 2000 BCE to 3000 AD at the link below.
What myths or folklore are associated with lunar eclipses?
In 413 BC during a lunar eclipse Syracusians staged an attack on and defeated the Athenians. In 1504, Christopher Columbus used a lunar eclipse to trick some Jamaicans in to giving him and his crew food and supplies.
How often does a lunar eclipse occur?
Lunar eclipses occur about every 6 months, when the Moon passes through the shadow of the Earth. The cycles of the moon's orbit determines whether an eclipse is partial or total.
The maximum number of lunar eclipses that can occur in a calendar year is three, and the maximum number of solar eclipses is 5 (minimum 2). However, these numbers are very rare. On average, there are 1-2 lunar eclipses (partial or total) and 2-3 solar eclipses (partial, annular, or total) each year.
However, during a solar eclipse the Moon's shadow does not cover the entire surface of the Earth (because the Moon is smaller than the Earth). So not everyone on Earth will see the solar eclipse as it occurs. Instead, only those living along the path of the Moon's shadow (called the path of totality) will see it. On the other hand, everyone will be able to see a lunar eclipse. Thus, it is far more common for people to see a lunar eclipse at any given location than a solar eclipse. The average time between two solar eclipses seen from the same location is about 360 years while the average time between two lunar eclipses seen from the same location is between 6 and 12 months.
Twice a year, there is a roughly 38-day window of time during which an eclipse could occur. These windows do not occur at the same time every year, so the term "season" does not refer to a particular time during the calendar year (Spring, Summer, etc.). The two eclipse seasons are separated by just under 6 months. Thus, the complete eclipse cycle lasts for roughly 345 days while the calendar year lasts for 365 days, so the eclipse seasons shift earlier and earlier each year - realigning again every 19 years.

A lunar eclipse occurs when the Moon passes through the Earth's shadow, which can only occur when the Moon is on the opposite side of the Earth from the Sun - which would normally be when we would see a Full Moon. Therefore, lunar eclipses can only occur during a Full Moon. Similarly, a solar eclipse occurs when the Moon passes in front of the Sun casting its shadow upon the surface of the Earth. This can only occur when the Moon is on the same side of the Earth as the Sun - which would normally be when there is a New Moon. The reason we don't normally get eclipses during Full and New Moons is because the Moon's orbit is tilted with respect to the Earth's orbit. During a Full Moon, the tilted path of the Moon usually takes it above or below the Earth's shadow and thus we get no lunar eclipse and just a normal Full Moon. During a New Moon, the tilted path of the Moon usually makes it such that the shadow of the Moon is cast above or below the surface of the Earth and thus we get no solar eclipse and just a normal New Moon.
However, during the two eclipse seasons the Moon's orbit is titled in such a way that it passes through the Earth's shadow and directly across the line of sight between the Earth and the Sun. If the Moon passes into a Full or New phase during this time an eclipse will occur. If a lunar and solar eclipse occur during the same season, they will be separated by about two weeks (the time it takes for the Moon to move from the opposite side of the Earth to the same side of the Earth as the Sun).

It can be anywhere from one to five in a year. During the 100 years
of the 20th Century, they averaged 2.29 per year.
Do ligers only occur in captivity?
Yes (they are because they are lion and a tiger together and lions and tigers are carnivores)
Yes, the liger is mainly carnivorous, but ingests grass as well, usually to aid in digestion.
What is the difference between a lunar eclipse and a solar eclipse?
Lunar eclipses occurs at a full moon when Earth is directly between the moon an the sun and also occurs only when there is a full moon because the moon is closet to Earth,s shadow at that time while a solar eclipses occur when the moon passes directly between Earth and the sun, blocking sunlight from Earth and only occurs when a new moon blocks your view of the sun.
During a lunar eclipse the shadow of what celestial body blocks your view of the moon?
It depends on the time of day, and year, and solar cycle. Its never the same exact point. In a total eclipse, the photosphere (and everything inside that, such as the core) is blocked by the moon but the corona is visible.
Can you ovulate on two different days in the same month?
No, although you can release multiple eggs you will only ovulate within one 24 hour period within your menstrual cycle. If TTC you should consider using fertility awareness method to determine exactly when you're fertile and when you ovulate, even when not TTC fertility awareness method is very useful for learning more about your body and it can be used as an effective birth control method.
There are many options available for blinds that will fit the E150 model. It's important to measure the windows accurately to ensure a proper fit. Consider purchasing custom-made blinds for the best fit and style. You can browse online or visit a local home improvement store to find a variety of blind options.
How many years apart are eclipses?
Eclipses generally occur at intervals of 6 months, with a minimum of 2 and a maximum of 7 eclipses in a calendar year. Each year typically has at least 2 solar and 2 lunar eclipses, occurring approximately 6 months apart.
A lunar eclipse occurs when the Moon passes through some part of the Earth's shadow. This only happens when the Earth, Moon and Sun are aligned. The Earth passes between the Sun and the Moon, casting its shadow on the Moon
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow).
A lunar eclipse occurs when a satellite, usually a moon, moves so that the planet is between the sun and the satellite so that the planet blocks the light from the star from reaching the satellite.
Will standard 480i cable programs look OK on HDTV?
Yes. They will not look "bad" by any means, but it won't look fantastc either. It mostly depends on your service provider. Time warner is the worst picture quality out there. then comes comcast. Then the top of the line stuff, for cable anyway, is Verizon Fios.
How does the lunar eclipse affect a fiddler crab?
To answer this question I did some on site research. I visited the Astronomy Marine Science Center in Chesapeake Bay, France. Dr. Francois Gerard gave me a fascinating tour of the facilities. I saw the zero gravity center where scientists put endangered marine life in a zero gravity oxygenless, waterless environment to see what happens. To date their success is extraordinary. After the gravity center I saw the breeding on the moon simulator. They have recreated the exact conditions of the surface of the moon, and they try to cross breed endangered marine life. Dr. Gerard said the experiments were going particularly well. Finally, he showed me the lunar eclipse wing of the facility. At that moment they had just received a shipment of fiddler crabs. For those of you who dont' know a fiddler crab is the one with the one huge claw. This oversized claw is used to better play coral and other natural marine instruments. Hence the name fiddler. Dr. Gerard oversaw putting the crabs in the eclipse tank. He than blocked the moon from the crabs conciousness and observed what happened. At first nothing happened, but after a few minutes the crabs became agitated. They started attacking one another. They formed differed ethnic groups based on the color of their claws. Soon they have developed advance crab weapons and were arranging battle formations. One group of crabs started a bombardment of heavy artillery fire, while a second group of crabs advanced upon the enemy crabs. The enemy crabs used their superior air power to cripple the artillery fire, but were unprepared for the commando crabs. The commando crabs attacked with their crab weapons and took out the enemy crabs almost to the last one. Having prepared every detail of the attack they even arranged with a deal with some of France's top seafood restaurants. Within minutes some chefs showed up to pick up the dead crabs which be used for tonight's assortment of crab dishes. Dr. Gerard told me the experiment was a qualified success and he was excited to the do the next eclipse experiment with endangered dolphins. He said he had secured a lucrative deal with Japanese sushi restaurants. My plea to you my fine wikianswers friends is to donate to the Astronomy Marine Science Center. Their work is crucial for future breakthroughs in space/marine research, which we all know deeply affects on a day to day basis. Let's all make a point to think more about space and dolphins in the same sentence this year. We'll make a better world through this.
What is the difference between a solar eclipse and a lunar eclipse?
A solar eclipse is when the sun is blocked from view due to the moon passing exactly in front of the sun as it circles around the globe. However, since the earth moon and sun do not share the same orbital plane, this happens very rarely. You MUST wear special protective eye covering to directly observe a solar eclipse or you risk causing serious injury including blindness. Sunglasses, however good they are, DO NOT PROTECT YOUR EYES during a solar eclipse. Don't directly observe a solar eclipse unless you have guaranteed that your eye wear is certified to protect you.
A lunar eclipse is when the moon and sun are on opposite sides of the globe, and the moon is full. At this time, when the earth blocks sunlight from reaching the moon this is called a lunar eclipse. The moon will often appear red during a total lunar eclipse. For the same reason as a solar eclipse, this also happens very rarely, but more frequently at a given location than solar eclipses. It is safe to observe a lunar eclipse without any special protective covering for the eyes. Just remember that if you are looking at an eclipse at night, it is safe to view.
What is the difference between a solar and lunar eclipse?
"A solar eclipse occurs when the Moon passes between the Earth and the Sun. Since the Moon and Sun appear to be the same size in the sky, the Moon can completely block the Sun if the relative positions of the Moon and the viewer are just right. Even though any place on Earth is subject to seeing an eclipse at one time or another, the area of the Earth which will perceive any particular eclipse as total is relatively small. The rest of the Earth will either see it as a partial eclipse, or will miss it altogether.
A lunar eclipse occurs when the Earth passes between the Sun and the Moon. Since the Earth's shadow is larger than the Moon, the Moon can be completely blacked out. Actually, a total lunar eclipse rarely blacks out the Moon completely. Light refracted through the Earth's atmosphere into the shadow area will usually give it a strange dark red glow. The other difference from a solar eclipse is that every place on Earth that can see the Moon at the time of the eclipse will see more or less the same thing.
Obviously, a solar eclipse will occur at the time of a New Moon, and a lunar eclipse at the time of a Full Moon."
Just something i found
hi diffrent person here i thought id sum this up for you ^ the difference between them both is that a lunar blocks earths sunlight from reaching the moon while a solar blocks sun from earth when the moon passes directly between the sun and earth. hope this helps you
When will the next lunar eclipse happen?
See the Sources and related links for NASA web page covering past and future eclipses both lunar and solar.
In 2013 there will be two penumbral eclipses (hardly noticable)
How do you change to Aux on a eclipse model CD3434?

How do you change a water pump 1996 Mitsubishi eclipse?
Here is the procedure, according to the service manual. Sorry, I could not import the figures to reference.
For the 1.6L SOHC:
DESCRIPTION
The water pump on this vehicle is attached to the rear of the power steering pump to form an assembly
(Fig. 27). The water pump/power steering pump assembly is located on the front corner of the engine
(Fig. 29).
The water pump is bolted to the rear of the power steering pump. Driven by the power steering pump
shaft, the water pump's impeller is located inside a die-cast aluminum housing. The water pump housing has a built in outlet. The water pump also has a bolt-on inlet cover with two ports, one for incoming coolant from the radiator and the other for incoming coolant from the heater.
Both pumps (water and power steering) can be serviced separately. Remove the entire water pump/
power steering pump assembly, then disassemble it to service either pump.
For information on the power steering pump, (Refer to 19 - STEERING/PUMP - DESCRIPTION).
REMOVAL
NOTE: Before proceeding, review all Warnings and Cautions (Refer to 7 - COOLING - WARNING) and (Refer to 19 - STEERING - WARNING).
(1) Disconnect battery negative (-) terminal.

(13) Remove the bolt fastening the power steering pressure hose to the reservoir bracket (Fig. 28).
(14) Back out the tube nut securing the power steering fluid pressure hose to the power steering pump and remove the hose from the pump (Fig. 28). Cap off hose end and pump pressure port.
(15) Remove coolant outlet connector hose at water pump outlet.
(16) Remove all four power steering pump mounting bolts. (Fig. 29)
(17) Remove power steering pump and water pump as an assembly.
(18) To separate the power steering pump from the water pump, (Refer to 7 - COOLING/ENGINE/WATER PUMP - DISASSEMBLY).
(19) If the power steering pump pulley needs to be removed, (Refer to 19 - STEERING/PUMP - DISASSEMBLY).
DISASSEMBLY
(1) Remove the three hex drive bolts and washers that attach the power steering pump to the water
pump (Fig. 27).
(2) Use the following steps to access the water pump impeller hex.
(a) Place a 1⁄4 inch drive 10 mm socket in through the coolant inlet tube, then back it into the heater hose fitting area as shown (Fig. 30). Backing the socket into the heater hose fitting makes it easier to perform the following step.
(b) Holding the socket in this position, insert a 1⁄4 inch drive extension (6 inches in length or longer) in through the heater hose fitting into the rear of the 10 mm socket.
(c) Push the socket with the extension into the pump placing the socket on the hex built into the
center of the water pump impeller.
(3) While holding the power steering pump shaft from turning using a hex wrench in the pulley end of
the shaft, loosen the impeller by rotating the 1⁄4 inch drive extension counterclockwise using a ratchet. The water pump will rise off of the power steering pump as the impeller is rotated.
(4) Once the threads have been disengaged, remove the entire water pump assembly from the power steering pump. If the water pump will be used again, the 10 mm socket and extension can be left inside the water pump until reassembly is completed.
(5) If the water pump inlet cover needs to be removed, remove the seven fasteners around the perimeter of the pump and remove the cover. Discard the housing O-ring type seal.
(6) If the power steering pump pulley needs to be removed, (Refer to 19 - STEERING/PUMP - DISASSEMBLY).
NOTE: For reassembly, (Refer to 7 - COOLING/ENGINE/WATER PUMP - ASSEMBLY).
ASSEMBLY
(1) If the water pump inlet cover needs to be installed on the water pump:
(a) First apply Mopart Dielectric Grease or equivalent to a NEW water pump O-ring seal.
(b) Place the O-ring seal in the housing groove where the cover contacts the housing.
(c) Install the seven fasteners around the perimeter of the pump. Tighten them to 12 N·m (105 in.lbs.) torque.
(2) If a pulley needs to be installed on the power steering pump, (Refer to 19 - STEERING/PUMP -
ASSEMBLY).
(3) Place the water pump assembly onto the power steering pump shaft.
(4) Rotate the water pump so the water pump outlet is near the water pump upper mounting holes
(hole with dowel guide). Arrange the three pump fastener holes so they line up.
(5) If the water pump impeller hex has not been accessed with a socket, use the following steps to
access the water pump impeller hex.
(a) Place a 1⁄4 inch drive 10 mm socket in through the coolant inlet tube, then back it into the heater hose fitting area as shown (Fig. 30).
(b) Holding the socket in this position, insert a 1⁄4 inch drive extension (6 inches in length or longer) in through the heater hose fitting into the rear of the 10 mm socket.
(c) Push the socket with the extension into the pump placing the socket on the hex built into the center of the water pump impeller.
(6) While holding the power steering pump shaft from turning using a hex wrench in the pulley end of
the shaft, tighten the water pump impeller rotating the 1⁄4 inch drive extension clockwise using a ratchet. This will draw the water pump in toward the power steering pump. Tighten the impeller to 26 N·m (19 ft. lbs.) torque.
(7) Remove the 10 mm socket, 1⁄4 inch extension and ratchet from the water pump. Remove the hex
wrench.

(Accents are intrusions of a mother language into an acquired language, as when a Mexican or Russian speaks English. Dialects are variations of a language, such as British English, Australian English, American English and so on with each of these huge dialectical entities having subdialects in them.) According to MSN Encarta, "Dialects develop primarily as a result of limited communication between different parts of a community that share one language. Under such circumstances, changes that take place in the language of one part of the community do not spread elsewhere. As a result, the speech varieties become more distinct from one another. If contact continues to be limited for a long enough period, sufficient changes will accumulate to make the speech varieties mutually unintelligible. When this occurs, and especially if it is accompanied by the sociopolitical separation of a group of speakers from the larger community, it usually leads to the recognition of separate languages. The different changes that took place in spoken Latin in different parts of the Roman Empire, for example, eventually gave rise to the distinct modern Romance languages, including French, Spanish, Portuguese, Italian, and Romanian." For specifics on how the Southern dialect emerged and is viewed today, the following is an interesting discussion: http://www.pbs.org/speak/seatosea/americanvarieties/southern/sounds/ For specifics on how the Southern dialect differs from Standarad American English, see http://en.wikipedia.org/wiki/Southern_American_English.
