12 January 2016 - Las Cruces, NM

A "one time comet" - this comet is expected to be ejected from our Solar System after passing the Sun. Its closest approach to Earth was on 17 Jan 2016.

Imaged the morning after my "normal" imaging session - after a "glitch" when collecting for a DSO. Actual image date was morning of 13 Jan 2016 (~5:30AM), however I normally record the evening that I setup/go out. Light pollution in my city really hurt this one.
