I've put an initial summary of the progress of the latest outburst and a
comparison with the three previous significant outbursts on the BAA
website here:

If anyone has any images of the comet between Nov 14.5 and Nov 15.5
please let me know. We have a pretty good outburst light curve but it
would be nice to fill in the gaps.

Nick.
