Comet Catalina US10
in the Evening sky - Night of orbital plane crossing
3/26/16

 
 This
            comet has slowed down considerably against the starry background,
            enabling more direct processing of a stationary comet in a nice
            star filled field. Now at mag 10.5, this comet was at orbital
            plane crossing tonight, but no trace of an anti tail was seen
            here. Still, the teal coloration in the head remains and a silky
            gossamar tail follows.
