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.

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.
