We observed the field of GRB230414B (D'Ai et al. GCN 33612

) with the 0.5m Virgin Island Robotic Telescope (VIRT) at the University of the Virgin Islands' Etelman Observatory on 04-16-2023 starting at 01:37:00 UT (T+33.4 hrs). We performed a series of exposures in R filter with a total exposure of 2900 s. The weather conditions were mixed during the hours of observation with an average airmass of ~1.3.

We do not detect the source identified by others (Pankov et al., GCN 33615

) and report the following 3-sigma upper limit:

T_mid               ||Exposure     ||Filter      ||Limit
T+35.1 hrs       ||2900s            ||R              ||>20.5

The limit is estimated from comparison to nearby USNO B1 stars and is not corrected for Galactic extinction. The VIRT is still in the
commissioning phase.
