TITLE: GCN CIRCULAR NUMBER: 36573 SUBJECT: GRB 240529A: AKO Optical Afterglow Detection DATE: 24/05/30 07:19:31 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), Nidhal Guessoum, Dalya Akl, Ilmah Aabdi, and Shaikha AlShamsi (American University of Sharjah, UAE), report:
We observed the field of GRB 240529A (Eyles-Ferris et al., GCN 36556), with our 0.36m f/7.7 robotic telescope. The observation started on 29 May 2024 at 21:57 (UT) to 30 May 2024 at 00:23 (UT), about 20.2 hours from the trigger.
We obtained multiple 180-sec exposures in Ic and Clear filters. We clearly detected the optical afterglow at: R.A. (J2000): 22:21:25.97 Dec. (J2000): +51:33:42.6
Our detection is consistent with the results of (Kumar et al., GCN 36559; Fu et al., GCN 36561; Shilling et al., GCN 36562; Perez-Garcia et al., GCN 36563; Dutton et al., GCN 36568; Mo et al., GCN 36569).
The following observations were calculated using Atlas catalogue as a reference: ---------------------------------------------------------------------------- - ObsTime (mid), Exposure (sec), Filter, Mag ---------------------------------------------------------------------------- - 2024-05-29T23:08:00Z, 24 x 180s (stacked), Ic, 17.9 +/- 0.10 2024-05-29T23:11:00Z, 24 x 180s (stacked), C, Sr = 18.9 +/- 0.07 ---------------------------------------------------------------------------- -
The magnitudes are not corrected for galactic extinction.
