The QSO 4C+10.45 was detected in a bright Gamma-ray state on 2025-05-25 by Wagner et al.(ATel #17206).
Optical follow-up with the 30 cm telescope of the S. Lucia di Stroncone Observatory (MPC 589) was performed on May 25, 29, and 31 with the BVRI Bessell filters. In the B images the source was detected but poorly measurable, while in the other filters was well measurable and found much brigther than the quiescent level reported in the PanSTARRS-DR1 catalog. Here are our findings:
2025-05-27T23:39 V=17:50, R=17.01, I=16.52; 2025-05-29T22:24 V=17:28, R=16.86, I=16.42; 2025-05-31T01:48 V=16.74, R=16.26, I=15.64. The source appears very active and brightening, further optical follow-up is encouraged.
