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

We observed the field of the GRB 230816A (Siegel et al., GCN 34450) with
our 0.36m f/7.7 robotic telescope. We obtained 21 x 180 sec. images in a
clear filter on 16 August, from 19:05 to 20:36 UT.

We detected the afterglow (Jiang et al., GCN 34453; Moskivitin et al., GCN
34456; Pankov et al., GCN 34457) in our stacked images with the coordinates
(J2000) R.A.= 21:53:47.01, Dec.= +37:51:16.7 and the brightness of Mv =
20.6 +/- 0.27 (t_mid - t0 = 3.7 hours).

The magnitude is not corrected for galactic extinction.
