We will be attempting to observe Comet PanSTARRS C/2011 L4 on the 12th March 2013 at the Pavilion. The comet will be 11 degrees above the horizon at 19:00, close to Uranus; the Sun - according to StaryNight pro 4.5 sets at 19:00 so we will want to set up any equipment before sunset.

This will be a challenging observation, the comet is predicted to be close to its brightest but it will be in bright twilight
CAUTION SUN MUST HAVE SET BEFORE YOU USE YOUR BINOCULARS
