Swift Observations of GRB 161015A

P. D'Avanzo (INAF-OAB) and M. De Pasquale (MSSL-UCL) for the Swift team

1. Introduction

Ohno et al. (GCN Circ. 20054) reported the GRB detection. At 17:03:07.04 on October, 15, 2016 Fermi-LAT detected high-energy emission from GRB 161015A, which was also detected by Fermi-GBM (trigger 498243790 / 161015710). Table 1 contains the best reported positions from Swift.

Table 2 is a summary of GCN Circulars about this GRB from observatories other than Swift.
