1. The problem statement, all variables and given/known data *A star on the celestial equator has right ascension of 16h00m00s. At what time of day will this star be at it's highest point, on Febuary 29th 2016. * 2. Relevant equations HA = LST - RA 3. The attempt at a solution When LST=RA, it'll be at it's highest point. How do I determine LST? There are many different explanations online. As a rough estimate, solar is off from sidereal by 4 minutes. 0 hour is on March 20th. Subtracting 4 minutes per day for 20 days gives me a difference of about 80 minutes. So it'd be 16h - (80minutes), roughly 2pm?
