Determine the latitude of the pole φ, if it is known that the luminary with declination b = + 20 ° and right ascension a = 30 ° stood in 2h star time at an altitude of h = 50 °.
Sidereal time s = 2h, a = 30o = 2h, therefore, the star was in the upper culmination; then b = f – z, or f = b + z = 20o + 90o – 50o = 60o (s. w.).
