This year, there will be a considerably good chance to combine the Messier marathon with an all-planet marathon, i.e. you can observe all solar-system planets during this night, though Neptune and Venus might be difficult. Probably, some comets brighter than about mag 14.0 will be visible; we will list them below, based on the JPL List of Currently Visible Comets:
Comet RA (2000.0) Dec mag March 16, 2002The list is RA ordered and thus in the sequence the comets might be observed from evening through midnight to morning.
Also, meteors from various showers may occur, and depending on your location, you may be able to observe the International Space Station, ISS.
