SUBJECT: GRB 210524B: Fermi GBM Final Real-time Localization
DATE: 21/05/24 11:30:50 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 11:20:34 UT on 24 May 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210524B (trigger 643548039.686002 / 210524473).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 148.5, Dec = 7.8 (J2000 degrees, equivalent to J2000 09h 54m, 7d 47'), with a statistical uncertainty of 4.8 degrees.
The angle from the Fermi LAT boresight is 92.0 degrees.

SUBJECT: Fermi GRB 210524B: DDOTI Upper Limits on the Afterglow

William H. Lee (UNAM), Océlotl López, Diego Gonzalez (UNAM), Alexander
Kutyrev (GSFC/UMD), and Srihari Ravi (ASU), report:
We observed the field of the likely long Fermi GRB 210524B (trigger
643548039, GCN #30074, Fermi GBM Team) with the DDOTI/OAN wide-field imager
at the Observatorio Astronómico Nacional on Sierra San Pedro Mártir (
http://ddoti.astroscu.unam.mx) on 2021-05-25 from 03:32:24 to 04:48:24 UTC
(16.19 to 17.46 hours after the event).
We observed a region of 20.4 degrees in RA by 20.4 degrees in declination,
with a 3 x 2 grid, centered on the Fermi GBM Final Position RA: 148.460
DEC: 7.79 (J2000 degrees). This region contains 6 instrumental fields or
about 400 square degrees. We obtained 600 to 720 seconds of exposure per
instrumental field in the w filter. We obtained AB photometry by
calibration against the APASS catalog.
We detect no likely candidate for the afterglow to our 10-sigma upper
limits of w = 18.52 - 18.84 (inter-quartile).
We thank the staff of the Observatorio Astronómico Nacional in San Pedro
Mártir.
