Nova in Perseus

[JeremyS]

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

The position of the object (noted by Seiji Ueda ) is RA 04 29 18.84 Dec +43 54 23.2 (J2000.0)

Follow up photometry and spectroscopy is encouraged.

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

28 cm SCT (C11) f/6.3, Starlight Xpress SXVF-H9 CCD
Exposure 200 sec

Mag ca 10.2. Field 0.29° x 0.22°. S at top, E to right.

Sketched the nova this evening. Appears to have brightened. I estimated the magnitude to 9.5 - 10.0.

Nova image, inspite of the bright Moon trying to ruin things for me!

Image scale 76' x 50' arc

I had the nova at mag 8.9 at 18.30 this evening

Quick grab from last night before some clouds rolled in.

This is how it looked through the Star Analyser (20sec exposure, 2020-12-05). Nice bright Hydrogen Balmer emission lines

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.

Currently around 9 mag.

The ARAS forum has details, and spectra:

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

(AAVSO data  dates month/day)

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 🙂

Hadnt spotted this. Fingers crossed for some clear skies so I can bag another nova

[bomberbaz]

Has anybody got a sky map of it that I can relate too please stellarium would be great. 

EDIT, found it in stellarium (Hip 20947), cheers.

So it is showing on Stellarium. I didn't know that it now updates itself with live data !

[Paz]

Thanks for all the replies, I have got a couple of AAVSO charts printed (a finder chart and a close up) and I'm ready!

[Wyvern]

Still easily visible.
