10th magnitude Nova in Perseus discovered on November 25!

Seiji Ueda (Hokkaido, Japan) reports the discovery of a transient object in Perseus at mag 10.6 on Nov 25.807 (TCP J04291884+4354232). It appears to have a large outburst amplitude of 9.2 mag and has been confirmed as a classical nova via spectroscopy by U. Munari (INAF Padova), F. Castellani, S. Dallaporta, V. Andreoli (ANS Collaboration).

There was an independent discovery by Stanislav Korotkij, Kirill Sokolovskij, and Olga Smolyankina, also at 10.6, on Nov 25.8438

Follow up photometry and spectroscopy is encouraged.

I took a CCD image I took of the nova just after it was announced last night:

Does anyone know the current magnitude or how quickly this is expected to recede, I will have a go at this with the VX14 if it is still doable.

Novae can be unpredictable in their decline 

For example nova Cas 2020 has been rebrightening repeatedly for 4 months now

but nova Del 2013 faded over 2 months

I had the nova a mag 8.5 last night. So it's technically a binocular object - or certainly a small telescope.

For CCD photometry I've had to stop my C11 down to about a C3 🙂
