Does astronomical twilight end near the summer solstice when observed from Greenwich England?
No. Around the Summer Solstice, "astronomical twilight" lasts all night for everywhere in England.
The southernmost point in England is Lizard Point, in Cornwall, at 49 degrees 57 minutes North.(Call it 50 degrees even, to make the math easier.)
Around the Summer Solstice on June 21, the Sun is at a declination of 23 degrees 26 minutes. (Let's round that off to 23.5 degrees.) At midnight, the Sun is at 23.5 degrees North over the Pacific Ocean. That means that from Lizard looking north at midnight, the Sun is (90-50) + (90-23.5) degrees = 40+ 66.5 degrees =106.5 degrees away. That means that the Sun is 106.5-90 degrees below the horizon.
"Astronomical Twilight" is defined as the Sun being less than 18 degrees below the horizon. On June 21, the Sun is only 16.5 degrees below the horizon at Lizard, and less than that anywhere else in England.
So around the Summer Solstice (about a week either side of it, actually) the Sun is never more than 18 degrees below the horizon from anywhere in England, Scotland or Ireland.
What is the color of the sunset and sunrise when a typhoon is coming?
While there are no specific colors of the sky that are associated with typhoons, this old folk saying is generally accurate;
"Red sky at night, sailors' delight
Red sky at morning, sailors take warning!"
That will depend on what else the weatherman says; normally, it'll be clear in context. But generally, they are talking about sunrise to sunrise.
If the weatherman on TV at 10PM says "The high today WAS 25, and the low tonight WILL BE 10", then he's reporting the actual high temperature, and his forecast for the low in the next 12 hours. Please note that the lowest temperatures sometimes come shortly after sunrise; overnight fog can insulate the ground from the worst of the cold, but the first rays of dawn can burn off the fog and allow the temperature to go down a bit more.
Are the minutes of daylight gained constant each day?
No, they are not constant at all. The duration of sunlight varies in a sinusoidal pattern, with the amplitude of the pattern set by your latitude. The change in daylight also increases and decreases, depending on your date and your latitude.
Look at the link below to the US Naval Observatory's web site to times of sunrise and sunset for an entire year. Enter your location, and it will calculate the times of sunrise and sunset for a complete year. You can see that near the solstices, the day length changes by less than a minute over the course of a week, while near the equinoxes, it changes by several minutes each day!
How many hour of daylight in north Norway in April?
On April 1, in Tromso, Norway:
Sun and Moon Data for One DayThe following information is provided for Tromso (longitude E19.0, latitude N69.5):Tuesday 1 April 2014 Universal Time + 1h
SUN
Begin civil twilight 03:46
Sunrise 04:50
Sun transit 11:48
Sunset 18:49
End civil twilight 19:53
So, about 14 hours of sunlight. Which seems right; on the equinox, on March 21, every place in the world (except the poles themselves) get 12 hours of sunlight. April1 is only ten days later.
Now jump to the end of the month and see the changes!
Wednesday 30 April 2014 Universal Time + 1h SUNSunrise 02:29 Sun transit 11:41 Sunset 20:58
NO twilight entries; twilight doesn't end and the sky never gets dark. In Russia, they would call this the "white nights". There are 5.5 hours of "white night", with 18.5 hours of daylight.
Go forward another 17 days. On May 17, the Sun rises at 0029 and sets
23 hours later at 2306.
On May 18, the Sun rises at 0013, and sets again ...... 69 DAYS later,
at 2320 on July 25.
Why the time of hanging is before the sunrise?
The time of hanging before sunrise is often seen as a more effective deterrent as it can have a greater impact on the community. It can also act as a visual deterrent, sending a strong message to potential wrongdoers about the consequences of their actions. Additionally, carrying out punishments before sunrise may also be a way to avoid public unrest or disturbances.
What is the time of the sunrise of earth on June 21 2013?

What time is sunset in Phoenix on November 30 2013?
Sunset in Phoenix on November 30, 2013 was at 5:17 pm local time.
It's simply due to the Earth's spinning.
Areas near the equator have only about twelve hours of daylight, along with about 12 hours of night, each day.
Away from the equator this equal balance of daylight and night happens only around times called the "equinoxes".
No, but like everywhere on the nordic hemisphere the night is longer than the day for half a year. Above the arctic circle, the sun doesn,t show at all in the darkest period. In Tromsø, the sun is below the horizon from November 25th to January 15th.

Why does the sun appear red at the time of sunrise and sunset?
The Sun doesn't really change color, it just appears that way. When the Sun is lower, closer to the horizon, the white light has to travel through more of the Earth's atmosphere. Refraction scatters the blue end of the spectrum more (which is why the sky is blue). The red color of light is scattered the least, and that is what you see on the horizon and in clouds.
Smoke, as from forest fires, makes the Sun look red for the same reason. The ash clouds from the Mount St. Helens volcanic eruption provided some of the most beautiful sunsets for a long time afterward.
Yes, it is still possible to see some stars in northern Scotland during June and July, even though it stays light for longer hours. However, the visibility may be limited due to twilight and the extended daylight hours during this period. You may have better chances of seeing stars during the darkest hours around midnight.
Why does it get dark late in Europe?
It depends on where in Europe you are and what time of year it is. Europe is near the North Pole, so in summer it can be bright quite late, but in winter it is dark much earlier. The closer you are to either of the poles, the more difference there is between the extremes of light and darkness there is in summer and winter.
What time will the sun set in Tulsa Oklahoma on September 22 2013?

Why does it seem to get darker quicker in mountainous areas than in areas with plenty of flat land?
The sun dips below the tops of the mountains, and throws shadows that make it appear that night is closing in. On flat land, the sun is above the horizon much longer, so there are no shadows and the sunlight lasts until the sun is well below the horizon.
What can go wrong if you try to micromanage every minute of the day?
Micromanaging every minute can lead to increased stress and burnout for both yourself and your team. It can also stifle creativity, productivity, and innovation by not allowing team members to make decisions on their own. This approach can also damage trust and morale within the team.
How do you tell when it is sunrise and sunset?
Generally, if it is dark outside and it gets lighter, the Sun is rising. If it's bright outside and then it gets dark, that was sunset.
Officially, "sunrise" is when the upper limb of the Sun comes into view on the horizon, and "sunset" is when the upper limb of the Sun disappears behind the horizon.
Where are sunrise and sunset at the same time?
No. Sunrise and sunset are only at the same time in countries that are on the equator. Greece is not on the equator. I asked your question on ask.com and it said that today sunrise in Greece is at 6:23 AM and sunset is at 8:39 PM.
