I found a possible nova on the M31 images made by Tamás Tordai in the evening 2026. Jan. 20.  It seems this is AT 2026afr, discovered by the XOSS team almost one and a half days ahead uf us.   

I've just found a possible nova on the 25x120s unfiltered images of Tamás Tordai made this evening (2026. Jan. 18.61785UT). It seems this is the due eruption of recurent nova M31N 1926-07c.

I've just found  a bright possible nova on my 4×90 s images of M31 taken on 2026 Jan 13.8280 UT with the 0.43 m CDK at Alnitak Remote Observatory. It was already faintly visible in the green channel of my 6×120 s colour images obtained with the 0.28 m RASA telescope at UDRO on 2026 Jan 12.3102 UT. This appears to be an independent detection of the transient AT 2026xf . Unfortunately, the XOSS team discovered it approximately 8 hours before my observations with the 0.43 m CDK . The discovery image (reference image subtracted).   Prediscovery image made with the 28cm RASA at UDRO (green channel).

I've just found a 18.4CV mag bright possible nova on my images taken with the 0.43m CDK reflector of the Alnitak Remote Observatory on 2026. Jan. 08.82UT. The guest star has significantly brightened during the night is, and it was clearly visible at around 17.8CV mag on my 3x120s. images at UDRO on 2026. Jan. 9.1928UT. It seems this is an independent discovery of AT 2026gs .  Our ATEL on the independent discovery of M31N 2026-01a . Subtracted image if Vend81 taken with T11 (a 51cm CDK at UDRO).    The discovery image.

I've just found a quite bright (16.5-17.0 mag) possible nova in my recent M31 (2025. dec. 15.1196UT) photos. It seems this is a independent discovery of  AT 2025agwf . The ISSP group found this quest star around 9 hours ahead of me. My images show that AT 2025agwf has significantly brightened since yesterday evening. Nothing was visible on my images taken on 2025. dec. 13. morning hours. Co-ordinates of AT 2025agwf : 00:43:17.640 +41:14:20.10 (J2000.0)

I've just found a ~19.4 C mag possible nova on my 4×90s co-added images of M31 taken tonight (2025 Dec 11.7759 UT) with a Luminance filter using the 0.43 m Dall-Kirkham telescope at the Alnitak Remote Observatory, Sierra del Segura, Spain. Follow-up images obtained this morning (2025 Dec 12.2138 UT) with a 0.61 m f/6.5 CDK reflector at the Sierra Remote Observatory, Auberry, California, USA (iTelescope.net) show that it is still rising, at around 18.3 CV mag. It has been reported to the TOCP website as PNV J00421476+4117284 and to the TNS server as AT 2025agmm . Preliminary coordinates of Vend78 : 00 42 14.76 +41 17 28.4 (J2000.0) Vend78 at 2025. dec 12.2138UT on 3x120s co-added images made with a 0.61-m f/6.5 CDK reflector, Sierra Remote Observatory at Auberry California USA (iTelescope.net). The discovery was made using the Alnitak Remote Observatories robotic telescope network, ARTA program.
