I've just found a fairly bright (~17.7 mag) possible nova on my recent M31 images made with the 0.43 CDK of Alnitak Remote Observatory on July 20.1813UT. Nothing was visible at this position on my 4×120 s images obtained with the 0.61-m CDK telescope at Sierra Remote Observatory, Auberry, California (iTelescope.net), on 2026 July 16.4384 UT, with a limiting magnitude of approximately 19.2C. The discovery of Vend85  has been reported to TOCP website as PNV J00425536+4117270  and to the TNS server as  AT 2026vdo . Updated preliminary co-ordinates of Vend85:  00 42 55.97 +41 17 32.44  (J2000.0) The discovery image with reference subtracted.   The discovery image. The discovery was made using the Alnitak Remote Observatories robotic telescope network, ARTA program.

I've just found a quite bright (~18.0CV) possible nova on my M31 images taken this morning (2026 May 22.1380 UT) with the 0.43 m CDK at Alnitak Remote Observatory.. It seems this is  AT 2026nhw reported my the XOSS team around 9 hours ahead of me.  Checking my yesterday images, it was already visible on yesterday morning (2026 May  21.1465 UT) too , but then it was significantly fainter (~18.8CV), probably this is the reason I missed the discovery earlier. Thus I just have another independent discovery and prediscovery observations. The discovery image.    The discovery image with reference image subtracted.   Observations were made using Alnitak Remote Observatories robotic telescope network, Alnitak Research Telescope Access (ARTA) program.

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)
