TITLE: GCN CIRCULAR NUMBER: 35594 SUBJECT: Konus-Wind detection of GRB 240119A (short/hard) DATE: 24/01/22 15:40:27 GMT FROM: Dmitry Frederiks at Ioffe Institute <fred@mail.ioffe.ru> D. Frederiks, A.Lysenko, A. Ridnaia, D. Svinkin, A. Tsvetkova, M. Ulanov, and T. Cline, on behalf of the Konus-Wind team, report: The short GRB 240119A (Fermi-GBM detection: The Fermi GBM team, GCN 35583; AstroSat-CZTI detection: Joshi et al.: GCN 35589; GECAM-B detection: Zhang et al.: GCN 355921; IPN triangulation: Svinkin et al., GCN 35592) triggered Konus-Wind (KW) at T0=62945.465 s UT (17:29:05.465). The burst light curve shows a single emission pulse which starts at ~T0-0.032 s and has a duration of ~0.13 s. The emission is seen up to ~2 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB240119_T62945/ As observed by Konus-Wind, the burst had a total fluence of (8.1 ± 1.7)x10^-7 erg/cm^2 and a 16-ms peak energy flux, measured from T0-0.016 s, of (1.9 ± 0.4)x10^-5 erg/cm^2/s (both in the 20 keV - 10 MeV energy range). The spectrum of the burst (measured from T0-0.048 s to T0+0.080 s) can be described, in the 20 keV - 1.5 MeV range, by a power law with exponential cutoff (CPL) model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep) with alpha = -0.23(-0.32,+0.40) and Ep = 678(-141,+254) keV. All the quoted errors are estimated at the 68% confidence level. All the presented results are preliminary.
