We should do a correction. Simply everything is wrong. The picture doesn’t look like an artist’s impression to me, it looks like an image of another comet; the comet is very very dim (one 2019 obs on COBS ~ mag 17, and perhaps unreliable); the time of best visibility is not 21:15 BST (02:45 BST, 36deg alt due east in astro darkness for me). Where is this information from??????
