Mohammad Odeh (Al-Khatim Observatory, AKO, operated by the International
Astronomical Center in Abu Dhabi, UAE), and Shaikha Alshamsi, Nuha Manal
Pattani, and Nidhal Guessoum (American University of Sharjah, UAE), report:
We observed the field of EP241107a detected by EP-WXT (Zhou et al., GCN
38112), with our 0.36m f/7.7 robotic telescope. The observation started on
07 November 2024 at 15:40 (UT), 90 minutes from the trigger.
We obtained multiple 180-sec exposures in Ic filter. We detected
uncatalogued object at:
R.A. (J2000): 02:20:02.45
Dec. (J2000): +03:20:02.2
The following observation was calculated using Atlas catalogue as a
reference:

Using The Dark Energy Survey (DES) catalogue, there is a galaxy at this
location of magnitude i=22.6, which could be the hosting galaxy.
The magnitude is not corrected for galactic extinction.
