5 July 2025, Jingyuan Zhao, a possible nova in M31, AT 2025qlt (= PNV J00433254+4132306).
3 July 2025, Róbert Fidrich and Tamás Tordai (HAA/VSS), a possible nova in M31, AT 2025qdc, PNV J00425628+4114512 (Vend60). Confirmed spectroscopically by Claudio Balcon on Belluno Telescope in Italy.
28 June 2025, Jingyuan Zhao, a possible nova in M31, AT 2025qea (= PNV J00425282+4105317).
20 May 2025, Ziyang Mai, Jingyuan Zhao, Jianlin Xu, Mi Zhang, a possible nova in M31, AT 2025kvc, PNV J00422300+4116197 = M31N 2025-05d. Confirmed by A. Kumar,K. Ackley,M. Dyer et al. (The Gravitational-wave Optical Transient Observer; GOTO) and Nabeel Rehemtulla (CIERA,NU), Daniel Perley (LJMU) et al. (ZTF). AT 2025kvc reached 15.8 mag and is one of the brightest novae in M31 in recent years.
11 May 2025, Jianlin Xu, Jingyuan Zhao, Mi Zhang, two possible novae in M31 in the same image: PNV J00422646+4104000 = AT 2025kip = M31N 2025-05b, and PNV J00424614+4112388 = AT 2025kiq = M31N 2025-05c.

6 August 2024, Jingyuan Zhao, nova AT 2024rnm = PNV J00424486+4115420 = M31N 2024-08b
7 July 2024, Jingyuan Zhao, possible nova PNV J00424415+4116276, AT 2024pbp in the Andromeda Galaxy, M 31.
27 June 2024, Christopher Lloyd and Maxim Usatov, AT 2024lwu is a likely UGSU variable.
2023
14 January 2023, Maxim Usatov and Jeremy Shears, Outburst Behaviour of the Dwarf Nova CG Draconis, During the British Astronomical Association (BAA) 2022 campaign, 27436 photometric observations of the dwarf nova (DN) CG Draconis were made, with 106 eclipses recorded. . . . Given CG Dra is located above the period gap, it may represent a new intermediary subtype between SS Cyg and SU UMa-type stars, or provide support to superoutburst models that do not rely on eccentric accretion disks.
If you have made a discovery on one of our telescopes, please do let us know and we would be glad to add your record to this page.
