I would like to alert members to a bright (8th mag) nova in Cassiopeia discovered yesterday (March 18). It is a binocular object and well worth a look if you get clear skies. Here’s the story.

Yuji Nakamura (Kameyama, Mie, Japan) reported the discovery of a possible nova, PNV J23244760+6111140, on March 18.4236.

Tonny Vanmunster confirmed the transient at March 18.306 UT, V -band magnitude 8.95 +/- 0.03 (CBA Extremadura Observatory using a 0.40-m f/5.1 telescope and SX-46 CCD camera)

The Astronomers Telegram 14471 reports spectroscopic classification of the object as a classical nova (Hiroyuki Maehara (National Astronomical Observatory of Japan), Kenta Taguchi (Kyoto University), Yusuke Tampo (Kyoto University), Naoto Kojiguchi (Kyoto University), Keisuke Isogai (Kyoto University).

Nova Cas 2021 is located at RA 23 24 47.73 Dec +61 11 14.8 (J2000.0).

This is a bright nova (latest observations I’ve seen on the morning of March have it at 8th mag) and further observations are encouraged. The field is circumpolar from UK and it should be an easy binocular object. Charts and sequences are available from the AAVSO Variable Star Plotter: https://app.aavso.org/vsp/chart/?east=r ... type=chart
Note that you can scale and orientate the chert to your preference)

Follow the unfolding story of this nova on the BAA Forum: https://www.britastro.org/node/25814

Please submit your observations to the BAA Variable Star Section. It would be great to see your images on BAA Member Albums.

Thanks to the Society for Popular Astronomy, you can find good directions for locating this 8th magnitude target here:

It is a series of star maps that narrows down to the target.
