A.P. Beardmore (U. Leicester) for the Swift team

1. Introduction

Bissaldi (GCN Circ. 22407) reported the GRB detection. At 12:24:38.55 UT on 10 February 2018, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 180210A (trigger 539958283 / 180210517). 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.
