Mohammad Odeh (Al-Khatim Observatory, AKO, operated by the International
Astronomical Center in Abu Dhabi, UAE) and Nidhal Guessoum (American
University of Sharjah, UAE) report:
We observed the Fermi GRB 231104A field (Fermi GBM team, GCN 34937) with
with our 0.36m f/7.7 robotic telescope on November 4, from 17:12 to 18:22
UT (corresponding to 16.6 hours from the GRB trigger time) using (Ic)
filter. We obtained 24x180 second images.
We do not detect a source within the Swift-XRT error region around the
candidate X-ray source (Page et al., GCN 34938).
The following 5-sigma upper limit is calculated using the ATLAS catalog as
reference:
Ic = 19.7
