Unpredictable - a photo on Flickriver

Unpredictable

C/2019 Y4 (Atlas) had lots of potential to become a naked eye comet during late May. However, as seen before, comets can be very unpredictable. Around mid-March, observations indicated its brightening has slowed, and by early April there was speculation it was breaking up. This was confirmed with a closeup image taken on 11-April-2020, the same day as the one I acquired above.

Although the above image was 1st aligned on the stars and then combined (DSS) with comet aligned images, it coma is diffuse and elongated.
