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 GRB 241030A (Fermi GBM team, GCN 37955; Klingler et
al. & Neil Gehrels Swift Observatory Team GCN 37956; Beardmore et al. &
Swift-XRT Team GCN 37962) with our 0.36m f/7.7 robotic telescope. The
observation started on 30 October 2024 at 14:42 (UT), 8.9 hours after the
trigger.

 

We obtained 14x180s images using Ic filter at the position given by
Swift/XRT: 

R.A. (J2000): 22h 52m 33.30s

Dec. (J2000): +80d 26' 59.6"

 

We did detect an afterglow candidate at the above position at a magnitude of
Ic = 18.06 +/-0.15 for the stacked images. The magnitude was estimated using
the Atlas catalogue as a reference. The magnitude is not corrected for
galactic extinction.

 

Our observational result is consistent with those of Lin et al. (GCN 37966)
and those of the SVOM/C-GFT team (GCN 37970).
