Sky Map Guide

Every month, the sky appears to shift 30 degrees if we observe at a specific time. This phenomenon occurs because the Earth completes a single rotation about its own axis in 23 hours and 56 minutes, but for a fixed location on earth to face sun again it takes a full 24 hours (since the earth rotates around the sun also). The extra 4 minutes account for one extra degree of rotation and in 30 days we have 30 extra degrees of rotation. The SkyMap Guide describes a month to month correlation of the celestial map to the corresponding earth map.
