Abstract:
We report on the optical photometric follow-up of AT2025aiv conducted with the 0.68m Horten telescope, Horten Videregaende Skole, Norway through BHTOM.space system.

AT2025aiv was discovered on 2025-01-28 06:31:12.288 by GOTO as a transient located 1arcmin away from MCG +08-33-024 galaxy (z=0.040300) at 15.68 mag in L-GOTO filter (internal name GOTO25tl).

The BHTOM.space network coordinated the follow-up observations of the transient and the object was detected in the data collected with 0.68m Horten telescope located at the Horten Videregaende Skole in Norway. The observations conducted on 2025-01-31 6:14, 6:18, 6:22 UT showed the transient detected at 16.67+-0.01 mag (g-band), 16.87+-0.02 (r-band) and 16.99+-0.06 (i-band), respectively. Photometric data were standardised using Gaia Synthetic Photometry (GaiaSP).

Further details, future data and the full photometric dataset are available for download by registered users of the BHTOM.space platform.
