Thanks all,
If it is clear tomorrow (Sunday) morning and you can get to somewhere
with a flat SE horizon it is worth trying to pick the comet up. It rises
around 40 mins before sunrise at 51N and, given that it can be imaged in
the daytime, it should be reasonably easy to pick up using a camera.
From here (Chelmsford) it will be 6deg altitude at sunrise around 8am.
Visual observations will be much harder but please report if you try.
Nick.
