Monthly Observing Information
This page provides charts, and text concerning what is visible in the night sky during the month noted. All information is for Baton Rouge, Louisiana, but they can still provide useful information for most other areas of the U.S.A. Sky charts, Saturn ring plane, and Venus phase images are for Midnight, on the 15th day of the month. Sky charts are 100 degree field of view, and show objects down to 12th magnitude. Times in the Astronomy Lab 2 text information are in 24 hour format and have been adjusted for Daylight Savings Time. Subtract 12 hours from those over 12 to get the equivalent PM. RA and DEC given are for Epoch 2000.
NOTE: If you print this page out using your browser, be sure it is set to print black text or the background, or the white text will not print at all.
