I made a visual estimate of magnitude 4.4 of the nova overnight. Subsequent observations show that it has dropped further since.
Here is the updated light curve:
The observation under the cross-hairs is my last (magnitude 4.4) observation and the others in purple (click image to enlarge) are the estimates I’ve submitted to AAVSO so far.
Sebastian Otero’s latest forum reply asks whether the current fading will be the nova’s last one and suggests possibly not, given its erratic behaviour so far.
