The weather is staying good, so I'm still at it. (0.4m Ritchey-Chretien reflector at the University of Alabama observatory, SBIG STL-6303E camera, R filter, exposures 10-300 seconds lengthening as the main dust puff expands). Here's a series from Oct 26-30 local time (between 0200-0400 UT each date, which will be one later than local). I suspect that the symmetry of the main circular outburst is breaking with the outline fuzzing out on one side. Each image section is about 15 arcminutes N-S (out of the 20x30-arcminute field of the chip). These are quick-and-dirty logarithmic displays, with only dark subtraction done beforehand (mostly because my schedule has been hectic this week, but at least the bits are on disk).

(Edit: oops, I tried to add the timing information and ended up with a new post. Apologies.)
