Updated: At the time of the report, I only had jpg preview image, which prevented me from getting accurate dates and brightness. But in order to inform everyone as soon as possible, I can only estimate from the preview image. Now, I've got the raw BGO fits data and here are my updated measurements: Observation/Discovery time: 2024-12-13.00038 UTC; Magnitude: 18.55 ±0.13 CV; Coordinate: 00 45 28.82 +41 54 09.5. -----Jingyuan Zhao
