GRB 241029A: SVOM/VT optical afterglow observations

VT started to observe the field of GRB 241029A triggered by Fermi/GBM (Fermi GBM team, GCN 37932) and SVOM/ECLAIRs & SVOM/GRM (Schanne et al., GCN 37934; Wang et al., GCN 37935) via ToO observations started at 2024-10-29T21:41:18.43, about 19.2 hours after the burst. The VT conducted observations simultaneously in two channels: VT_B (400nm-650nm) and VT_R (650nm-1000nm). The counterpart (Jiang et. al. GCNa 37937; Lin et al., GCN 37939; Jiang et al., GCN 37940; Francile et al., GCN 37941; Ackley et al., GCN 37943; Odeh et al., GCN 37944; Moskvitin et al., GCN 37954; Saikia et al.,GCN 37961) was detected in both bands with VT_B=23.3+/-0.3 mag and VT_R=21.8+/-0.12 mag with a 2.2 ks exposed time of VT. The Space Variable Objects Monitor (SVOM) is a China-France joint mission led by the Chinese National Space Administration (CNSA, China), National Center for Space Studies (CNES, France) and the Chinese Academy of Sciences (CAS, China), which is dedicated to observing gamma-ray bursts and other transient phenomena in the energetic universe. VT was jointly developed by Xi'an Institute of Optics and Precision Mechanics (XIOPM), CAS and National astronomical observatories (NAOC),CAS.
