We report the discovery of two probable novae in M31 on a co-added 720-s R-band CCD frame taken on 2022 Apr. 12.128 UT with the 0.65-m telescope at Ondrejov.
Designations, positions, and offsets of the new objects from the M31 center are summarized in the following table:
TOCP designation CBAT designation R.A. (J2000) Dec. (J2000) Offset R.A. Offset Dec.
PNV J00424066+4116350 M31N 2022-04a? 00 42 40.66 +41 16 35.0 41.3" W 26.5" N
PNV J00431052+4119198 M31N 2022-04b? 00 43 10.52 +41 19 19.8 295.2" E 191.3" N
The following R-band magnitudes were obtained for the PNV J00424066+4116350 using the 0.65-m telescope at Ondrejov:
2022 Mar. 28.781 UT, [18.3; Apr. 12.128, 16.9 ± 0.15.
The following R-band magnitudes were obtained for the PNV J00431052+4119198:
2022 Mar. 28.781 UT, [18.8; Apr. 12.128, 17.6 ± 0.15.
As with all extragalactic novae, follow-up spectroscopic and photometric observations to confirm the nova's nature and determine its spectroscopic class and rate of decline (speed class) are encouraged.
