Nick, You must have a good unobstructed SE Horizon to catch C/2018Y1. I worked out that at that AZ I can see down to 12 degs Alt from my observatory. I would have needed to wait until 06.50UT for the comet to clear next doors roof, 10 mins into nautical twilight by which time the sky would have been just too bright… but perhaps I should have tried.
