About this image

Located on the extreme NW border of And and Cas. Visual limiting magnitude 5.5 and reducing during this short session. There is a lot of moisture in the air.

Comet is in the Milky Way, very many stars in the field. Not all have been plotted in the drawing.

This is a faint and inconspicuous object. Planetarium websites are suggesting it is 9^th mag.

At the start of the session it was visible with direct vision. By the end it needed averted vision as conditions worsened. I estimate the magnitude at no better than 13m. The comet has essentially no condensation, 1 on the standard DC scale. The observed motion is rapid, to the SW. moving to (b) by 18.44 UT.

The comet looked like a round mist but once or twice I had the impression of a broad fan, as shown in the inset.
