General information
GRB 260614A is reported as a likely long GRB detected at 2026-06-14 10:06:14.62 UT by Fermi/GBM, with additional detections by GECAM-B and AstroSat/CZTI. The Fermi/GBM on-ground position is RA = 192.76 deg, Dec = -38.51 deg with a statistical uncertainty of 6.04 deg.
Wavelength coverage
- Gamma-ray / hard X-ray: Fermi/GBM detected and localized the burst; GECAM-B detected it in about 70-6000 keV; AstroSat/CZTI clearly detected it in 20-200 keV.
- High-energy context: the angle from the Fermi LAT boresight was reported as 106 deg.
No observations are mentioned in optical, infrared, ultraviolet, radio, X-ray afterglow, neutrino, or gravitational-wave bands.
Lightcurve and spectrum
- GECAM-B reports that the burst mainly consists of multiple pulses with T90 = 20 +/- 6 s.
- AstroSat/CZTI reports the light curve peak at 2026-06-14 10:06:15.64.
- AstroSat/CZTI reports a peak count rate of 57 (+28, -14) counts/s above background in the combined data of three quadrants, with total counts of 391 (+196, -206).
- AstroSat/CZTI reports a local mean background count rate of 221 (+3, -3) counts/s.
- AstroSat/CZTI measures T90 = 20 (+3, -12) s from the cumulative CZT light curve.
