Star parties usually run from 9 to 11 p.m. The exception is the Sleeping Bear Dunes October Star Party which runs from 8 to 10 p.m. With that exception the median time will be 10 p.m. For objects on the celestial equator (0º declination). Easily observable objects would be plus or minus 5 hours right ascension of the sidereal time. For objects with south or negative declination the hours of visibility are less, and if positive the hours of visibility are more.

Approximate sidereal time (the right ascension of the sky on the meridian) at the first of the month at 10 p.m. Eastern Time

An addition to this writeup will be added soon. That is the period of visibility the object has based on its declination.


If you have objects that you feel should be on this list, email the particulars to info@gtastro.org or bob@bjmoler.org. The coordinates listed for objects on the table are for the equinox of 2000.0. If you don't know the coordinates, the object designation or name by itself is OK.
