We observed the field of GRB241025A detected by Swift (Ambrosi et al., GCN 37859

), Fermi (Fermi GBM team, GCN 37860

), SVOM (SVOM/GRM team, GCN 37863
Not found
 
 
), and EP (Li et al., GCN 37864
Not found
 
 
) with the 0.5m Virgin Island Robotic Telescope (VIRT) at the University of the Virgin Islands' Etelman Observatory on 2024-10-25 starting at 22:37:31 (T-mid ~T0+21.8 hrs). We performed a series of exposures in an R filter with a total exposure of 2800s. The weather conditions were partly cloudy during the hours of observation with an average airmass of 2.4. 

We do not detect any source within the enhanced XRT position (Goad et al. GCN 37868
Not found
 
 
). This non-detection is consistent with detections  (Jiang et al. GCN 37862

) and upper limits  (Lipunov et al. GCN 37873

) reported by others. We report the following 3-sigma upper limit:


T_mid                ||Exposure   ||Filter   ||Limit 
T+ 21.8 hrs          || 2800 s    || R       || > 19.8

The limit is estimated from comparison to nearby PANSTAARS and is not corrected for Galactic extinction. The VIRT is still in the commissioning phase.
