SCAS – Southern Colorado Skies / January 10 – 16, 2016

Consider a planetarium program to help you plan your observations. There are many commercial products available, and a very good program (Cartes du Ciel) is available free at http://www.ap-i.net/skychart/en/start.

THIS WEEK

Comet Catalina (C/2013US10) is still in view – see http://earthsky.org/space/comet-catalina-c2013-us10-november-december-january-2015-2016 and the “finder chart” I posted a couple weeks ago. The comet is now between Arcturus and the handle of the Big Dipper. It’s an early morning target – at 2 a.m. it should be in a good viewing spot. Use binoculars because it’s a relatively faint 6th magnitude.

First quarter is a great time to view the moon because the craters and mountains along the meridian stand out so well in contrast. Here is a basic map of the Moon.

Can you find these objects? Binoculars or a low-power telescope are all that you need!
