What are 5 things an astronomer does in a day?

Astronomers do many different things, depending on what type of a facility they work in. Five things that an astronomer might do in a typical day -- or night, since many astronomers don't start work until after dark -- is to observe the planets through a telescope, check for Doppler changes in the stars, search the sky for objects that have changed position recently, maintain the telescope, and perform calculations based on their observations.
