I found this problem in the "Introduction for the Modern Astrophysics". I'm stuck with this problem because I don't know how to relate the right ascension and latitude.

Try to think about what part of the sky is above the horizon at night for an observer at 40 degrees north latitude in January. You need to use not just the latitude, but the time of year and the time of day. Remember that you can't see the stars during the daytime.
