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 9th 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.
