Circular_text TITLE: GCN CIRCULAR NUMBER: 24662 SUBJECT: GRB 190525A: Fermi GBM Final Real-time Localization DATE: 19/05/25 00:57:35 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely SHORT GRB At 00:45:47 UT on 25 May 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190525A (trigger 580437952.651712 / 190525032). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 338.0, Dec = 5.5 (J2000 degrees, equivalent to J2000 22h 32m, 5d 30'), with a statistical uncertainty of 4.0 degrees. The angle from the Fermi LAT boresight is 43.0 degrees.

Circular_text TITLE: GCN CIRCULAR NUMBER: 24665 SUBJECT: GRB 190525A: Insight-HXMT/HE detection DATE: 19/05/27 00:07:03 GMT FROM: Ce Cai at IHEP C. Cai, S. Xiao, Q. Luo, Q. B. Yi, C. K. Li, X. B. Li, G. Li, J. Y. Liao, S. L. Xiong, C. Z. Liu, X. F. Li, Z. W. Li, Z. Chang, X. F. Lu, A. M. Zhang, Y. F. Zhang, C. L. Zou (IHEP), Y. J. Jin, Z. Zhang (THU), T. P. Li (IHEP/THU), F. J. Lu, L. M. Song, M. Wu, Y. P. Xu, S. N. Zhang (IHEP), report on behalf of the Insight-HXMT team: At 2019-05-25T00:45:47.65 (T0), Insight-HXMT/HE detected GRB 190525A(trigger ID: HEB190525031) in a routine search of the data, which was also triggered by Fermi/GBM (GCN #24662). The Insight-HXMT/HE light curve mainly consists of single pulse with a duration (T90) of 0.90 s measured from T0-0.20 s. The 1-ms peak rate, measured from T0+0.53 s, is 1719 cnts/sec. The total counts from this burst is 753 counts. URL_LC: http://www.hxmt.org/images/GRB/HEB190525031_lc.jpg All measurements above are made with the CsI detectors operating in the regular mode with the energy range of about 80-800 keV (deposited energy). Only gamma-rays with energy greater than about 200 keV can penetrate the spacecraft and leave signals in the CsI detectors installed inside of the telescope. Insight-HXMT is the first Chinese space X-ray telescope, which was funded jointly by the China National Space Administration (CNSA) and the Chinese Academy of Sciences (CAS).

Circular_text TITLE: GCN CIRCULAR NUMBER: 24667 SUBJECT: GRB 190525A: AstroSat CZTI detection DATE: 19/05/27 08:49:16 GMT FROM: Prachee Ghumatkar at IUCAA/AstroSat P. Ghumatkar, V. Sharma, T. Khanam, D. Bhattacharya and A. Vibhute (IUCAA), V. Bhalerao (IIT-B), A. R. Rao (TIFR) and S. Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration: Analysis of AstroSat CZTI data showed the detection of a short GRB 190525A, which was also detected by Fermi GBM (GCN #24662), Global MASTER-Net (GCN #24663) and Insight-HXMT/HE (GCN #24665). The source was clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range at 00:45:47 UTC. The CZTI light curve shows a weak detection in the 40-200 keV energy range. CZTI GRB detections are reported regularly on the payload site at http://astrosat.iucaa.in/czti/?q=grb. CZTI is built by a TIFR-led consortium of institutes across India, including VSSC, ISAC, IUCAA, SAC and PRL. The Indian Space Research Organisation funded, managed and facilitated the project.
