We observed the optical counterpart to EP241107a (Zhou et al., GCN 38112) with the Goodman High Throughput Spectrograph mounted on the SOAR telescope in imaging mode (Prop. ID: SOAR2024B-021). We took two 300s exposures each in g, r and i-band between 2024-11-11T03:05:18 and 2024-11-11T03:38:26 UTC corresponding to ~3.5 days after the initial trigger.
Our observations do not reveal the optical counterpart associated with EP241107a (Odeh et al., GCN 38115; SVOM/C-GFT team, GCN 38116; Lipunov et al., GCN 38117; Mohan et al., GCN 38118; Busmann et al., GCN 38120; Adami et al., GCN 38122; Quirola-Vasquez et al., GCN 38126; Li et al., 38127; Odeh et al., GCN 38128; Kong et al., GCN 38131; Zheng et al., GCN 38136; Pankov et al, GCN 38147). With photometric calibration using the Pan-STARRS1 catalogue, we provide the following AB magnitude upper limits:
g > 22.4
r > 22.9
i > 22.7
