Swift Observations of GRB 220310A

1. Introduction

Negoro et al. (GCN Circ. 31725) reported the GRB detection. The MAXI/GSC nova alert system triggered on a bright uncatalogued X-ray transient source at 2022-03-10T00:27:57 UT. Table 1 contains the best reported positions from Swift.

Lipunov et al. (GCN Circ. 31732) reported the position from MASTER for the optical afterglow of this GRB. Table 2 is a summary of GCN Circulars about this GRB from observatories other than Swift.
