TITLE: GCN CIRCULAR NUMBER: 38115 SUBJECT: EP241107a: AKO Optical Afterglow Detection DATE: 24/11/07 16:22:43 GMT FROM: Mohammad Odeh at Al Khatim Observatory M44 mshodeh@gmail.com

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:

---------------------------------------------------------------------------- -

ObsTime (mid), Exposure (sec), Filter, Mag

---------------------------------------------------------------------------- -

2024-11-07T15:53:50Z, 9x180s (stacked), Ic, 17.85 +/- 0.18

---------------------------------------------------------------------------- -

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.
