The photometry of the transient in Messier 31 field: GMG observation
Abstract
We followed the GCN circular on the discovery of an optical %transient as a new blazar candidate in the Messier 31 field (Gianluca %et al. GCN 34819). We observed the transient with the 2.4-meter %optical telescope at Gao-Mei-Gu (GMG) station of Yunnan %Observatories. The preliminary results are shown as %---------------------------------------------------- UT %filter mag ---------------------------------------------------- %2023-10-17T14:16:13.243 B 20.14 ± 0.12 %2023-10-17T14:19:54.225 V 17.80 ± 0.09 %2023-10-17T14:23:29.236 R 18.44 ± 0.06 %2023-10-18T16:12:25.346 B 20.68 ± 0.15 %2023-10-18T16:16:00.356 V 18.13 ± 0.10 %2023-10-18T16:19:35.370 R 18.89 ± 0.07 %2023-10-19T15:37:25.492 B 20.23 ± 0.10 %2023-10-19T15:41:07.493 V 17.62 ± 0.06 %2023-10-19T15:45:03.473 R 18.38 ± 0.04 %2023-10-20T15:17:30.676 B 20.24 ± 0.13 2023-10-20T15:21:09.646 V 17.71 ± 0.08 2023-10-20T15:24:49.624 R 18.41 ± 0.05 2023-10-21T15:12:50.704 B 19.83 ± 0.15 2023-10-21T15:16:30.683 V 17.77 ± 0.09 2023-10-21T15:20:08.724 R 18.26 ± 0.06 2023-10-22T14:27:55.829 B 20.54 ± 0.16 2023-10-22T14:31:36.818 V 17.87 ± 0.10 2023-10-22T14:35:17.806 R 18.90 ± 0.06 ---------------------------------------------------- The further identification is ongoing.
