LCOGT g'-band image of AT 2023yoa (ULL-ASTRO-MASTER-8)

Observation with the Las Cumbres Observatory 40 cm telescope 0m4-06, equipped with an SBIG camera,
at the Las Cumbres Observatory node at Haleakala Observatory on 2023-11-28 05:23:01 UT
(180 sec exposure in the SDSS g' filter).

Possible a recurrent nova PNV J00430954+4115399

Due to poor image quality in the early morning, we reprocessed and measured the target, and found that it corresponds to PNV J00430954+4115399 (=M31 2013-10c). We suspect the target is a recurrent nova.

Prediscovery image

AT 2023yoa was faintly visible on a 720s co-added image made on  2023-11-27 03:14:54.240 UTC with reference image subtracted. Unfortunately it's not visible on the on the original image, just on the subtracted.

The original 6x120s images were made remotely with a Luminance filter on a 0.43m telescope Utah Desert Remote Observatory at Great Basin Desert, Beryl Junction, Utah, USA (iTelescope,net network).
