Asteroid / Comet Gault
in the Morning sky
January 12, 2019

 
 This
            18.8 magnitude asteroid in Crater is currently demonstrating
            a dust appendage. The origin of the sudden dust tail appearance
            is currently being debated, and future studies of this very rare
            type of object will no doubt answer this question. Here is a
            short set of exposures with the 10 inch Orion Astrograph and
            ST10xme CCD for 40 minutes total time.
