We were unlucky then Nick. At the Haw Wood star party this weekend just gone
it wasn't visible at all in a 16" and extremely faint in Owen's 22". We were
unfortunate in being between outbursts. The skies were very damp which
didn't help with transparency.

Subject: [BAA Comets] Possible 12P outburst on or before Nov 14.75

Morning all,

I've just measured my 12P images from last night using Astrometrica and it
is around 2 magnitudes brighter than three days ago measured in a 9 arcsec
aperture.

On Nov 11.77 using this aperture I had mag 14.5. Last night in 20 minutes
around Nov 14.75 the comet rose from 13.6 to 12.5.

Can anyone confirm?

Nick.
