I imaged the comet from Chelmsford again this morning and it was
considerably brighter than yesterday. I get the following total
magnitudes and coma diameters with comphot using a 51mm, f/4.9 refr. +
ASI2600MC. Green channel vs Gaia G DR3:

2025 April 5.157	9.6	2.3'
2025 April 6.150	8.0	3.8'

Transparency was probably a bit better this morning but conditions and
time were similar.

Interesting behaviour so please observe this comet if you can and submit
magnitude estimates. It is still on the PCCP so no official designation yet.
