Maps are produced using
Cartes
du Ciel Sky Charts Version 3.9 Beta
Northern Hemisphere
uses Oklahoma City as the observation point. Southern Hemisphere
uses Rio de Janeiro as the observation point
unless
otherwise indicated. All times are UT Evening Twilight
Astronomical. The Sky Maps will be
updated daily for the following day.
They
are a close representation of what you would see in the sky for
this time period. Yet slight variation could be possible
depending on your exact location. All
maps are using Alt/Az
Coordinate System, unless
otherwise indicated.

| Celestial Notes for March 2013 |
| The warmer nights of spring bring a panoply of new stars and constellations for skywatchers to enjoy. Leo is in good view by nightfall, climbing straight up from the eastern horizon, led by his bright “heart,” the star Regulus. Virgo follows the lion a couple of hours later. Auriga, the charioteer, is to the maiden’s left, marked by yellow-orange Arcturus, one of the brightest stars in the night sky. The brilliant planet Jupiter dominates the evening sky, with the orange “eye” of Taurus close by. Some Information provided by: The University of Texas McDonald Observatory. Purchase their 2013 Sky Almanac for a year review of upcoming events. |

| Information |
| Alt/Az Coordinate System. The Alt/Az Coordinate System. is a celestial coordinate system that uses the observer's local horizon as the fundamental plane. This conveniently divides the sky into the upper hemisphere that you can see, and the lower hemisphere that you cannot (because the Earth is in the way). The pole of the upper hemisphere is called the zenith. The pole of the lower hemisphere is called the nadir. Alt/Az Coordinate are: * altitude (Alt), sometimes referred to as elevation, that is the angle between the object and the observer's local horizon. * azimuth (Az), that is the angle of the object around the horizon, usually measured from the north point towards the east. In former times, it was common to refer to azimuth from the south, as it was then zero at the same time the hour angle of a star was zero. This assumes, however, that the star (upper) culminates in the south, which is only true for most stars in the Northern Hemisphere. The Alt/Az Coordinate System. is sometimes also called the az/el or Horizontal Coordinate System. UT Evening Twilight Astronomical Astronomical Twilight begins when the Sun's center is 18 degrees below the horizon. Civil Twilight begins when the Sun's center is 6 degrees below the horizon; Nautical Twilight begins when the Sun's center is 12 degrees below the horizon. |
