Check out Cloudy Nights. In their Forums/Announcements and News/Celestial Events (http://www.cloudynights.com/), there is a monthly post by Dave Mitsky titled “Celestial Calendar”. It gives a great summary of upcoming celestial sights. For example, this month he mentions a double Galilean transit of Jupiter’s Ganymede and Io for tomorrow night. He also notes ” The Curtiss Cross, an X-shaped illumination effect located between the lunar craters Parry and Gambart, is predicted to occur at 2:33″ on January 28th. Neat stuff and fun to ramble through while planning what to observe.
