Like everything else in astronomy, "it varies". Most cycles are sinusoidal; they go up and down at varying rates. When it is at the top or bottom of the cycle, it's hardly changing at all. When it is at the middle of the cycle, it can change pretty quickly.
I'm going to refer you to the Online Nautical Almanac, and you can look up the magnitude of the change for the day you're interested in. Let's look up today, August 10, 2013.
Today, 8/10/2013, it looks like the Moon's declination is moving south at about 10.7 minutes per hour. But by 8/15/13, the Moon's declination will be moving south at only 2.5 minutes per hour.
What else can I help you with?
Where geographically is magnetic declination the worst?
Magnetic declination is typically worst near the magnetic poles, particularly within the Arctic and Antarctic regions. In these areas, the angle between magnetic north and true north can vary significantly, leading to more pronounced declination values. Additionally, regions with complex geological structures or significant magnetic anomalies, such as areas with large mineral deposits, can also experience heightened declination effects.
What is the angle of Polaris above the horizon at New Orleans Louisiana?
The angle of Polaris above the horizon is the same as the latitude from which you are trying to measure it. Hollywood Florida has a latitude of ~26 degrees, so Polaris is 26 degrees above the northern horizon.
Along which latitude lines are the deserts in africa located?
South Africa and Australia share the range of latitude from about 22.12° to 34.83° South. Any 'line' or parallel at a latitude withing that range crosses both of those countries.
Does the declination of the North Celestial Pole change with location?
No. The declinations of the various stars are fixed, and don't vary over time. The declinations of objects within our solar system, such as the Sun, Moon and the planets, will vary as each of those objects move along in their own orbits around the Sun. And saying that "the declinations of stars don't change" isn't precisely correct, but they do not change within human lifetimes. Over the course of hundreds of years, these will vary slightly.
How many degrees above the horizon is the north star from longitude 39 degrees 53 ft and 49 inches north and latitude 76 degrees 9 ft 50 inches west at 5AM?
The "North Celestial Pole" of the sky is always due north of you, and at the same angle above your horizon as whatever your north latitude is. It doesn't move, and the north star is always within about 1/3 of a degree from that point. Your longitude makes no difference at all. And neither does the time of day. And feet and inches have no place in angle measure. And latitude is north or south and longitude is east or west.
What is the formula for calculating whether a star is circumpolar viewed from a northerly latitude?
To determine if a star is circumpolar (never sets) when viewed from a northerly latitude, you can use the formula: 90° - latitude + declination >= 0. If the result is greater than or equal to zero, then the star is circumpolar from that latitude. The declination is the star's angular distance north or south of the celestial equator.
A country you with latitude measurement of 50 degrees north lies within the?
A country with a latitude measurement of 50 degrees north lies within the northern hemisphere.
What two countries are located entirely within 0 degrees and 10 degrees north latitude 50 degrees and 60 degrees west latitude?
-- Suriname -- French Guiana
What is the longitude and latitude of Draco?
The constellation Draco is located at approximately 17 hours right ascension and 60 degrees declination. The exact coordinates will vary depending on the specific star within the constellation that you are referring to.
When does the Sun have declination 0 degree today but will have a negative declination tomorrow?
Declination is the angular measurement of a celestial body north or south of the "celestial equator". You can think of it as the equivalent of "celestial latitude". The "fixed stars" don't have any change in declination. (Well, they _DO_, but only very slightly and VERY slowly.) The Sun, Moon, and planets all have their own paths within the solar system, so their declinations will change on a day-to-day basis. The Sun is at a declination of zero precisely at the time of the equinox. In September, the Sun's declination is decreasing, and it goes negative immediately after the moment of the equinox. This is generally on September 21, but this can vary a day either way depending on the cycle of leap years.
What never sets at your latitude?
Any sky object within (your latitude) degrees of the north celestial pole.
What is the magnetic declination in Oregon?
The magnetic declination in Oregon varies depending on the specific location within the state. However, as a general guideline, it typically ranges between 14 to 16 degrees east. It's important to use updated resources or tools to obtain the most accurate magnetic declination value for a specific location.
What is the latitude of an observer if the altitude of polaris is 43 degrees?
If the altitude of Polaris is 43 degrees above the northern horizon, then the observer is located somewhere within roughly 1/2 degree of 43 degrees north latitude.
How country with a latitude measurement of 20 degrees lies within this?
There are a few countries that have a latitude measurements of 20 degree that runs across. Latitude measurements can be across the earth.
What continent falls between 40 degrees north latitude and 40 degrees south latitude?
I don't know but I thank it is the antarctic circle
Does California lie south 40 degrees latitude?
Yes, California lies south of 40 degrees latitude. The northernmost point of California is just above 42 degrees latitude, while the majority of the state extends southward well below 40 degrees. This places all of California within the southern hemisphere relative to the 40-degree latitude line.
23 degrees n latitude and 90 degrees east longitude?
These coordinates fall within Bangladesh, near or within the Gaurnadi subdistrict.
