The azimuth and altitude of any celestial body depend on the precise time and date, and on the observer's location.
I live in a suburb of Sacramento, CA, and the time right now is May 7, 2011 at 4:31PM Pacific Daylight Time. Procyon is, at this moment, at an altitude of 52 degrees 36 minutes, and an azimuth of 149 degrees 18 minutes; a little east of south. It is at a distance of 11.41 light years. Like most celestial objects, it tracks to the west at about 4 degrees per minute.
I get this data from the free planetarium program Stellarium, available at stellarium.org. If you download this program and program it with your exact location, you can get up-to-the-second calculations for yourself.
However, we don't generally refer to stars by azimuth and elevation; instead, we use the more common measurements of Right Ascension and Declination, numbers that do not change measurably over the span of a century. According to Wikipedia, Procyon is at:
Right ascension
07h 39m 18.1/17.7s
Declination
+05° 13' 29/20"
What else can I help you with?
What are the altitude and azimuth of a star that is now setting due west?
The point on the horizon that is due west has an altitude of zero and an azimuth of 270 degrees.
What are the altitude and azimuth of a star halfway between the horizon and zenith to the due east?
An object seen halfway between the horizon and the zenith has an altitude of 45 degrees.An object seen due east of the observer has an azimuth of 90 degrees.
What is the azimuth and altitude of the star Betelgeuse?
As of 2021, Betelgeuse has an azimuth of around 225 degrees and an altitude of about 27 degrees when observed from the northern hemisphere. These values will change throughout the night and over the course of the year due to the Earth's rotation and orbit.
What is the azimuth and altitude of Sagittarius?
The azimuth and altitude of Sagittarius depend where you are on Earth and the date and time. The altitude can be anything form 0-90, and the azimuth 0-180.
Which is smaller in size Procyon or Procyon B?
Procyon B is smaller in size compared to Procyon, as Procyon is a main sequence star (type F5IV-V) while Procyon B is a white dwarf companion star.
What will be the azimuth and altitude of a star which setting directly in the northwest?
Azimuth = 315° (True) Altitude = 0
What are the altitude and azimuth of a star that is now setting due west?
The point on the horizon that is due west has an altitude of zero and an azimuth of 270 degrees.
What are the altitude and azimuth of a star halfway between the horizon and zenith to the due east?
An object seen halfway between the horizon and the zenith has an altitude of 45 degrees.An object seen due east of the observer has an azimuth of 90 degrees.
What Azimuth and altitude are used to describe the star?
Azimuth is the horizontal angular distance measured clockwise from true north, while altitude is the vertical angular distance above the horizon. Together, these coordinates help locate a star's position in the sky.
What is the azimuth and altitude of the star Betelgeuse?
As of 2021, Betelgeuse has an azimuth of around 225 degrees and an altitude of about 27 degrees when observed from the northern hemisphere. These values will change throughout the night and over the course of the year due to the Earth's rotation and orbit.
Recording the location of a star requires a measurement of?
Recording the location of a star requires a measurement of altitude, azimuth, and time.
What is the azimuth and altitude of Sagittarius?
The azimuth and altitude of Sagittarius depend where you are on Earth and the date and time. The altitude can be anything form 0-90, and the azimuth 0-180.
If a star's azimuth is 90 degrees and its altitude is 45 degrees where is this star in the sky?
If a star's azimuth is 90 degrees, it is located directly east on the horizon. An altitude of 45 degrees means that the star is positioned halfway up in the sky, forming a right angle with the horizon. Therefore, this star would be visible in the eastern sky at an angle that is halfway between the horizon and the zenith.
Which is smaller in size Procyon or Procyon B?
Procyon B is smaller in size compared to Procyon, as Procyon is a main sequence star (type F5IV-V) while Procyon B is a white dwarf companion star.
What color of procyon star?
Procyon is a binary star system with two components: Procyon A is a yellow-white F-type main-sequence star, while Procyon B is a white dwarf.
Does the rotation of the earth affect azimuth and altitude?
The variation of the apparent azimuth and altitude of everything we see in the sky is the result of Earth's rotation.
Where in the sky would a star with an azimuth of 180 degrees and an altitude of 20 degrees be found?
A star with an azimuth of 180 degrees would be due south, and an altitude of 20 degrees would place it 20 degrees above the horizon. So, the star would be in the southern part of the sky, 20 degrees above the horizon.
