TITLE: GCN CIRCULAR NUMBER: 17824 SUBJECT: GRB 150514A: Further Swift observations DATE: 15/05/18 15:26:42 GMT FROM: Phil Evans at U of Leicester P.A. Evans (U. Leicester), M. de Pasquale (MSSL/UCL) and J. K. Cannizzo (GSFC/UMBC) report on behalf of the Swift team Swift has performed further observations of GRB 150514A (Kocevski and Arimoto, GCN Circ. 17816), collecting a further 2 ks of data, from T0+120.9 ks to T0+122.9 ks. The object previously detected in the XRT (Kennea et al. GCN Circ. 17818) and UVOT (Marshall & Cannizzo, GCN Circ. 17820) has faded in both instruments. The UVOT counterpart was detected with a white magnitude of 20.51 +/-0.15, which gives a power-law decay index of 1.63 +/- 0.15. The X-ray counterpart was detected with a count-rate of (1.04 +/- 0.03) x 10^-2 ct/sec, which gives a power-law decay index of 1.4 +/- 0.5, consistent with the slope measured from the UVOT data. This circular is an official result of the Swift team.
