A time-lapse video of the comet rising this morning is posted at http://blog.cajunastro.com/?cat=6

I was just about to suggest that ISON has caught up the ground it had lost earlier, but that last photo suggests it may have now exceeded that!  With ISON dropping in altitude, and the Moon swinging over into that part of the sky this could be the best chance of seeing it in the next 7 days.

Comet ISON's tail has grown very long indeed (7 degrees or more than 16,000,000 kiilometers), since the outburst.
