Abstract

We study the prompt emission properties of the long duration GRB200613A using Fermi-Gamma-Ray Burst Monitor (GBM) and Large Area Telescope (LAT) data. The prompt emission light curve of GRB200613A reveals a strong peak emission up to ∼ 50 s after the burst accompanied by an extended emission up to ∼ 470 s similar to that seen in ultra-long GRB light curves. The time-integrated spectroscopy shows that the Band function best fits the main emission episode, and the extended emission follows the power-law behaviour because of poor count rates. Due to its high isotropic energy and low peak energy, GRB 200613A lies at the extreme end in both the Ep–Eiso and Ep–T90 plots. In addition to the GBM detection, the Fermi-LAT detected the highest energetic photons of 7.56 GeV after 6.2 ks since burst, which lies beyond the maximum synchrotron energy range.
