Here is an image of the coma obtained around 78 hours after Thursday evening's outburst. It implies an expansion velocity of around 210 m/s.

This is a stack of 20x60s at 0".65 per pixel. The seeing was reasonably good (2".4 FWHM) but I have sharpened the image using an iterative Gaussian filter to try to bring out any detail in the coma. The central bright region is very star-like and there are suggestions of some features in the extended circular coma.
