The M81 nova monitoring collaboration reports the discovery of a probable nova in M81
on a co-added 2880-s unfiltered CCD frame taken on 2020 Mar. 22.952 UT with the 0.65-m
telescope at Ondrejov.
The object designated PNV J09561048+6902273 is located at R.A. = 9h56m10s.48,
Decl. = +69o02'27".3 (equinox 2000.0), which is 200.1" east and 87.8" south of
the center of M81 (see link to discovery image below).
Here we list the observing dates and corresponding photometry:
Date [UT] | Mag | Err | Filter | Telescope
2020-03-21.959 | <21.9 | | C | OND
2020-03-22.952 | 19.9 | 0.15 | C | OND
2020-03-24.064 | 19.7 | 0.15 | C | OND
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 CCD
camera (with a Kodak KAF-3200ME sensor and standard BVRI photometric filters)
mounted at the prime focus.
The unfiltered OND photometry was calibrated against R-band comparison stars from
Perelmuter & Racine (1995).
