When does the sun have adeclination of zero degrees today but will have a negative declination tomorrow?
The Sun has zero declination at the two equinoxes on March 21 and September 21 (approximately). At the autumn equinox in September it crosses the plane of the Earth's orbit from north to south, so its declination goes from positive to negative.
At what point is the sun at its minimum declination and at its maximum declination?
At the imaginary lines that we call the Tropics, the directly overhead sun reaches max / min.
The sun's declination migrates through?
The sun's declination migrates manually through 47 degrees latitude. It moves in the middle of the latitudes of Tropic of Cancer and Tropic of Capricorn.
What is the relationship between the time of year and the angle of the sun in the sky?
The angle of the Sun in the sky, its maximum height above the horizon, depends on a measurement called its declination, which varies over a range of ±23.5 degrees. The Sun's declination is zero at the equinoxes, and is +23.5 degrees at the summer solstice (in the northern hemisphere), the longest day, and -23.5 degrees at the winter solstice, the shortest day. Declination is the Sun's latitude on the celestial sphere, and the declination of any obect is equal to the latitude of a set of points along a line of latitude on the Earth's surface at which it passes overhead.
What seasons do equinoxes occur?
The year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses the Earth's equator.The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.

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.
At what point sun's declination is minimum?
This only happens on the fall equinox, the dividing line between summer and fall. If you live in the northern hemisphere, this happens on September 21 (plus or minus one day because of the cycle of leap years) and in the southern hemisphere on March 21.
At what point is the sun at its minimum declination and at its maximum declination?
At the imaginary lines that we call the Tropics, the directly overhead sun reaches max / min.
What was the Sun declination on March 20 2010?
At 12:00 Noon Eastern Time on 3/20/2010, the sun's declination was -0.025 degree.
What is the declination of the sun on the other side of the earth when there is a 0 declination here?
zero. The plane is contigous through the planet.
What does the sun's declination migrates through?
23.5 degrees
The sun's declination migrates through?
The sun's declination migrates manually through 47 degrees latitude. It moves in the middle of the latitudes of Tropic of Cancer and Tropic of Capricorn.
How does earths tilt cause the season?
The earth's tilt changes the declination of the sun, thus crating seasons.The sun's declination causes spring summer, fall and winter.
During which two times of the year is the declination of the sun changing most slowly?
The declination of the sun is changing most slowly at the time of the solstices, i.e., June 21 and December 21.

When is the sun located at 6 hours RA -23.5 degrees declination?
winter solstice
