TITLE: GCN CIRCULAR NUMBER: 38128 SUBJECT: EP241107a: AKO Optical Afterglow Follow-Up Observations DATE: 24/11/08 13:12:05 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:
Following up on our first observation (GCN 38115) of the field of EP241107a (detected by EP-WXT, Zhou et al., GCN38112), we report observations of the source over three time periods starting on 07 November 2024 at 15:40 (UT), 90 minutes from the trigger, with our 0.36m f/7.7 robotic telescope.
We obtained 30x180-sec exposures in Ic filter of the uncatalogued object detected at R.A. (J2000): 02:20:02.45, Dec. (J2000): +03:20:02.2.
The following table summarizes the results of the images, calculated using the Atlas catalog as a reference:
-----------------------------------------------------------------
ObsTime (mid), Exposure (sec), Filter, Mag
-----------------------------------------------------------------
2024-11-07T15:55:21Z, 10 x 180s (stacked), Ic, 17.95 +/- 0.19
2024-11-07T16:26:29Z, 10 x 180s (stacked), Ic, 18.11 +/- 0.24
2024-11-07T16:57:37Z, 10 x 180s (stacked), Ic, 18.48 +/- 0.25

The magnitudes are not corrected for galactic extinction.
