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.
