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 240905E (Dichiara et al., GCN 37397) with our
0.36m f/7.7 robotic telescope. The observation started on 5 September 2024
at 18:46 (UT), 21 minutes after the trigger. 

 

We obtained 29x180s images using Ic filter at the position given by
Swift/XRT: 

RA (J2000)  = 23h 03m 12.83s

Dec (J2000) = +35d 31' 25.6"

 

We did not detect any credible afterglow candidate at the above position
down to a magnitude of 19.13 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 An et al. (GCN 37399),
Moskvitin & Spiridonova (GCN 37401), Strausbaugh et al. (GCN 37403), Brivio
et al. (GCN 37408), and Adami et al. (37412).
