Mohammad Odeh, Osama Ghannam, Anas Mohammad, Khalfan Al-Noaimy, and Sameh
Al-Ashi, report on behalf of Al-Khatim Observatory (AKO) operated by the
International Astronomical Center in Abu Dhabi, UAE:

We observed the field of GRB 230824A (Page et al., GCN 34537; Navaneeth et
al., GCN 34538) with our 0.36m f/7.7 robotic telescope. The observation
started at 18:04 UT on 24 August 2023, 4.1 hours after the trigger.

We obtained multiple 180-sec exposures in R filter. We detected a bright
star with a magnitude of R=13.5 at:
R.A. (J2000): 17:27:43.32
Dec. (J2000): -16:12:19.2

Which is within the uncertainty radius of the localization determined by
Swift team (Page et al., GCN 34537), however, our detected object is a
transient object (AT 2023qql) which was discovered today at 14:37:22 (UT)
0.6 hours after the GRB trigger, so more observations are required to
confirm this link.
