GCN Circular 24052
K.L. Page (U. Leicetser) reports on behalf of the Swift-XRT team: Swift has performed a second follow-up observation of the ground-detected Swift-BAT GRB 190331B (Page et al., GCN Circ. 24041). An additional 2.7 ks of data were collected, entirely in Photon Counting mode, 334.5 ks after the trigger time The count rate of the possible afterglow counterpart ("Source 1") mentioned in GCN Circ. 24041 remains constant across both observations, at about 0.01 ct s^-1. We therefore conclude that we did not detect an X-ray afterglow for GRB 190331B. This is an official product of the Swift-XRT team.
