Grabbed a quick image soon after reading your post. On my members page at: https://britastro.org/observations/observation.php?id=20240731_135808_85400732e67d812d

very reddened by interstellar dustCheers
RobinI had a short break in clouds last night – 31st (before torrential rain and storms), and made a visual estimate of 10.2 with a 22cm. Might not be my best estimate, as struggling with Covid – and feeling pretty sorry for myself.

Get well soon Gary!

Hi all,
I uploaded a series of V mags to the database from last night. It was at around 10.7 V.
Cheers
Ian.This Nova now has the offical designation V615 Vul.
I’ve asked Andy to add this to the DB, in addition to N Vul 2024 and PNV J19430751+2100204.

Hi all,
It’s a very slow decline, almost steady over the past 2 nights.
Cheers

Hi all,
Eight consecutive nights from my C11 in Spain shown here – the graceful decline continues…
Cheers
IanAttachments:
So far it has followed a pretty linear decline. Well worth continuing to watch.
Attachments:
It is continuing to fade. For photometry it is worth checking that you don’t include the 15th mag star just west. There are also a few 17th and 18th mag stars within a few arcsec that will come into play as it fades. Attached image taken earlier this evening as it got dark.

Hi all,
I managed a few measurements last night. The slow fade continues.

Hi all,
I’ve been monitoring V615 Vul in R, V and B since early August and I’ve noticed in the last 5 or since days that the R and V mags have closed right up. See attached.
Not sure if this is of any significance?
Cheers

Hello Ian, the abrupt drop in R ~1.4 mag last week is intriguing. I presume reduction in H-Alpha emission. Be interesting if there are spectra from around the same to see what’s happening there. Jeremy

The spectra in the ARAS database
https://aras-database.github.io/database/novavul2024.html
seem to suggest an overall drop in both continuum and H alpha from 20240828-20240907 with H alpha increasing slightly relative to the continuumCheers

Hi all,
I must apologise. I have been wrongly using the B mags for my R filters since 5th September! I am in the process of replacing them in the database!
Ian.
