Recall from the lab we did that the position of objects seen in the sky changes slowly night by night. That's what it means on your star charts on the top axis when it lists the date. It is indicating what part of the sky is due south at 8pm on a given date. If you look at the sky at the same time every night, you will slowly see constellations drift out of view toward the west and come into view from the east. One complete cycle takes 365 days. If Orion is directly south, on the meridian, at 8pm, then exactly one year later, it will again be in the same place at the same time. This "one complete cycle" is 24 hours of right ascension, and it is also 360 degrees. Therefore, how much does the sky change in one single day? First give your answer in hours of right ascension. It will be a fraction of an hour, so convert it to minutes. Then give your answer in degrees. This calculation involves simple arithmetic and is easier than you think.
