Vend92: independent discovery of the possible extragalactic nova AT 2026abeq

Szerző:

Yesterday morning (Sept 10/11 night) I found a possible nova on my unfiltered M31 images made with the 43 cm CDK at the Alnitak Remote Observatory. While checking the relevant official website for recent discoveries, it turned out that the XOSS team had reported this guest star approximately 3.5 hours before me. So it goes.

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.

I've just discovered a bright (~16.411CV magnitudes) possible nova on my 8x120s co-added M31 photos taken at 2025. november 03.1914UT using the 0.61-m f/6.5 CDK reflector, Sierra Remote Observatory at Auberry California USA (iTelescope.net network).  The transiens was visible on all eight individual 120s images. The discovery of this transient has been reported as PNV J00424541+4115192 and AT 2025acfl respectively. Coordinates of Vend74 : 00 42 45.52   +41 15 18.8  (J20000.0). The astrometry was provided by Tamás Elek, Nyíregyháza-Oros, Hungary using the original discovery images).
