GRB 191221B: AGILE/MCAL observations
Abstract
The AGILE Mini-CALorimeter (MCAL) detected the long GRB191221B at T0 = 2019-12-21 20:39:11.42 (+/- 0.01 s) already detected by Swift (Laha et al., 2019; GCN #26534). In the MCAL energy range (0.4-100 MeV), the burst lasted about ~15 s and released a total number of ~12000 counts over a background rate of 650 Hz. The light curve shows several peaks and can be found at http://www.agilescienceapp.it/notices/GRB_065726_504045551.415264.png. The AGILE-MCAL detector is a CsI detector with a 4 pi FoV, sensitive in the energy range 0.4-100 MeV. Additional analysis of AGILE data is in progress.
