Comet C/2011 L4 (PanSTARRS)

Predicted positions of Comet PanSTARRS this week.

This week, starting tomorrow, Comet C/2011 L4 (PanSTARRS) will be reaching its perihelion, or its closest point to the sun.  Indeed, tomorrow evening, 12 March, it will be found in the evening just to the left of the waxing crescent moon.  This is a rather bright comet appearance that, if not visible with the naked eye, is certainly an easy binocular target.  As its name implies, it was discovered in 2011 by the PanSTARRS telescope in Hawaii -- and this is a non-periodic comet, so this is your only chance to see it!

For more information, you might note:

Comets may have once been a foreboding sign, but they remain impressive in any age!  Don't miss it!

Live well!
