Question

A star is observed to cross the meridian (due south) at an elevation of 34°, as seen from an observatory sited at a latitude of 42° north. What is the declination of the star? At the moment of transit, a clock running on Universal Time (UT) read 03 h 16 min 24 s. At the previous midnight, the sidereal time was 14 h 38 min 54 s. Calculate the Right Ascension of the star.

Step 1

The elevation of the star at meridian transit is given as 34°, and the latitude of the observatory is 42° north. The declination (δ) of the star can be found using the formula for the meridian altitude of a star: \[ \text{Altitude} = 90^\circ - \text{Latitude} + Show more…
