TITLE: GCN CIRCULAR NUMBER: 27825 SUBJECT: GRB200524A: UVOT detection DATE: 20/05/26 13:49:24 GMT FROM: Paul Kuin at MSSL N.P.M. Kuin (MSSL/UCL) and K.L. Page (U. Leicester) report on behalf of the Swift UVOT team Swift UVOT did a further follow up of the Fermi-LAT detected GRB200524A (Dirirsa et al. GCN Circ. 27797). We detect the afterglow discovered by Ho et al. (GCN Circ. 27799), ZTF20abbiixp, in the UVOT white filter in 5.4ks exposure taken between To+1.15d and To+1.57d, with white = 22.06 +/- 0.12 magnitudes (on the UVOT photometric system, Breeveld et al. 2011, AIP Conf. Proc. 1358, 373 ). The source does not vary significantly during these observations. No correction has been made for the Galactic reddening E(B-V)=0.02 (Schlafy et al., ApJ 737, 10, 2011)
