M31 with AT 2026aaom (Andromeda)
AT 2026aaom (Type: unk) discovered 2026-09-04.151 UT by Robert Fidrich Alias: Vend91 Discovery Magnitude 18.2 (Clear Filter) vs Prior Non-Detection Limiting Magnitude 19 (Clear Filter) Róbert Fidrich and Tamás Tordai (HAA/VSS) report the discovery of a new astronomical transient. Discovered using 4x90s co-added images made with a 0.43 m Dall-Kirkham telescope at Alnitak Remote Observatory, Sierra del Segura, Spain, with Luminance filter. This possible nova has also been designated as AT 2026zdb. Discovery images and more details: https://vendegcsillagkereso.blogspot.com/2026/09/vend91-quite-bright-possible-nova-in-m31. html The discovery was made using the Alnitak Remote Observatories robotic telescope network, ARTA program.
