Nice one Finbarr, good capture, this one is provoking a lot of interest as it’s spectrum is puzzling, I’m going to follow this as long as I can

Keith, there was a suggestion on the BAA forum that it night not be a nova, but it has since been confirmed -

Latest observation suggests it has dropped to mag 8 in less than 24 hours

Hi,

Great to see so many observations. I missed the peak due to cloudy weather. Last night (2021 Jun 23-24) I estimated it as mag 11.7, quite a decline from the 6th mag peak. The nova has received an official designation V1674 Her.

I would suggest submitting your observations to a variable star organization like the AAVSO or BAA VSS.

By the way, Nova Cas 2021 (V1405 Cas) is still bright.
