Thanks for that great chart and information Roman!. Let's keep adding any further data we get in the future to this thread. Thought I would copy you and Brian's comments on to this thread to keep everything tidy...
Took Feb 21 as "late Feb" & found dec -1 deg 16 min (and heading north), transit at 02:36 (from my site). So it's getting to a reasonable altitude from 55N. Saturn is nearby, stepping forward I found that the comet is about 1.2 degrees south south west of Saturn on Feb 24th (0300 UT), and estimated at mag. 6.0. Hopefully will be quite a reasonable show, at least up to 8P/Tuttle last year.
