How do you find the altitude and azimuth of a star?

Formula for altitude of star

  1. alt = angle of altitude of star.
  2. lat = latitude of observer.
  3. d = declination of star.
  4. H = hour angle of star = (t – RA)(360/24)
  5. RA = right ascension of star.
  6. t = local sidereal time.
  7. RA and t are measured on a scale from 0 to 24; the formula above converts the angle H to degrees (0 to 360 scale)

What is the azimuth of a star?

The azimuth of a star is how many degrees along the horizon it is and corresponds to the compass direction. Azimuth starts from exactly North = 0 degrees azimuth and increases clockwise: exactly East = 90 degrees, exactly South = 180 degrees, exactly West = 270 degrees, and exactly North = 360 degrees = 0 degrees.

What is the difference between altitude and azimuth with regard to the night sky?

Azimuth is measured eastward from the north point (sometimes from the south point) of the horizon; altitude is the angle above the horizon.

Which is the correct definition of altitude and azimuth?

Altitude and Azimuth 1 Altitude or elevation: The angle the object makes with the horizon. Objects that seem to touch the horizon have an… 2 Azimuth: The object’s cardinal direction, such as north, east, south, or west. It is specified as the horizontal angle… More

Is the constellation Cetus visible from both hemispheres?
