Special Projects

The Milwaukee Astronomical Society members participate in multiple special observing projects. The Variable Star Project on Z Ursae Majoris (Z UMa) is a good project to learn about variable star observing. Finder charts, commentary, and instruction appear on the links on the left.

Many astronomical observations require that the data be presented with Julian Dates. The following charts will display the Julian Date of the first of each month for the next two years.

Add 2,400,000 to get the full Julian Day. So, the full Julian Day for July 1st 2011 is 2455743. The Julian Day is a consecutive day count starting on January 1 of the year -4712 (= 4713 B.C.E.).
