Report on ATEL #15315:


The M81 nova monitoring collaboration reports the discovery of a probable
nova in M81 on a co-added 4590-s unfiltered CCD frame taken on 2022
Apr.6.810 UT with the 0.65-m telescope at Ondrejov. 

The object designated PNV J09554544+6905525 is located at 

RA 9h55m45s.44, DEC +69o05'52".5 (2000.0), which is 65.7" east and 117.4"
north of the centre of M81.

Here we list the observing dates and corresponding photometry: 

Date [UT]    |  Mag   | Err  | Filter  | Telescope> 

2022-04-03.817 | <21.5  |      | C       | OND  
2022-04-06.810 |  20.4  | 0.2  | C       | OND  

As with all extragalactic novae, follow-up spectroscopic and photometric
observations to determine the nova's spectroscopic class and rate of decline
(speed class) are encouraged. 

The OND 0.65-m is a reflecting telescope at the Ondrejov observatory
operated jointly by the Astronomical Institute of ASCR and the Astronomical
Institute of the Charles University of Prague, Czech Republic. It uses a
Moravian Instruments G2-3200 MkII CCD camera (with a Kodak KAF-3200ME sensor
and standard BVRI photometric filters) mounted at the prime focus.
