The observation was made on the night of 23-24 May.

I first mediated 3 images at a time and then added the 10 groups saved. In total they are 30x90sec with the Cassegrain of the Frasso Sabino observatory (diameter 369mm F/6.66 with the reducer / flattener). The image scale is 1".34 / pixel and a field of 22'.8x28'.5 with north at the top and east at the left.

The coma has a diameter of about 27" and its magnitude, obtained with the astrometric program using a radius of 10 pixels, is 15.1.
