Comet Johnson V2
in the Evening sky
May 20, 2017

 
 This
            bright 7th magnitude object in Bootes is near the zenith for
            most of the evening, and in a week the Earth will pass into its
            orbital plane. This image was taken with the wide field Stellarvue
            SV80 to hopefully capture the very faint gas tail. The comet
            was offset downward a bit to leave room for such a thing. A very
            weak gas tail is seen here pointing to the upper left coming
            from a teal colored core region. The dust tail is a brownish
            red color and is pointing to the lower left. We expect the dust
            tail to significantly be enhanced by the plane crossing and then
            the gas tail will be directly opposite of the dust one.
