I’ve just measured it as 7.54 (2021 June 13 22:51) compared to 5.94 at this time last night. Both unfiltered ref to Gaia DR2 G so somewhere between V and R. That’s a fall of 1.6 mags in day. That’s pretty fast. I remember photographing V838 Her (George Alcock’s last nova) in 1991 but only getting it on one occasion since it faded so fast.
