Jingyuan Zhao report/s the discovery of a new astronomical transient.
IAU Designation: AT 2026oir
Coordinates (J2000): RA = 00:42:38.680 (10.661167) DEC = +41:15:58.20 (41.266167)
Discovery date: 2026-06-05 02:56:11.904 (JD=2461196.62236)
Potential host galaxy: M31
Host redshift: -0.001004
Remarks: Jingyuan Zhao report discovery of a possible nova in M31. Image obtained by 0.43-m f/6.8 Corrected Dall-Kirkham robotic telescope at Alnitak Remote Observatories in Nerpio, Spain, exposured 200s with Clear filter, around 2026 Jun. 05.12236 UT, mag = 19.97 CV. It brightened to 18.92 CV in a confirmation image taken on Jun. 06.12053 UT using the same instrument and configuration. Observations were made using Alnitak Remote Observatories robotic telescope network, Alnitak Research Telescope Access (ARTA) program.
