Comet Catalina US10
in the morning sky
December 18, 2015

 This comet is getting much higer in the sky now, nearly 40 degrees up at 5am. The gas tail is getting very faint at this time however, and is seen as a nearly featureless ray extending to the upper right. The dust tail however is still bright and extends downwards forming an anti tail as the tail dust combines with the dust in the nearly edge on orbital plane.
