FIist frame of the sequence [UT 1030]

Last frame [1150UT]

For a comet a long way from the sun, at a pretty high inclination to the plane it has rather good tail. But when I went to look it up, I couldn't find it on any of the current lists [inthesky, stellarium]. No doubt I was looking in the wrong places.
I know that I am exposing myself to ridicule by not being able to identify this obvious comet, but I am intrigued and no doubt my AB friends will be able to help me.
