TITLE: GCN CIRCULAR NUMBER: 37414 SUBJECT: GRB 240905E: AKO Optical Upper Limit DATE: 24/09/06 14:38:50 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: 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).
