TITLE: GCN CIRCULAR NUMBER: 17569 SUBJECT: GRB 150311A: Konus-Wind trigger at 16:16:24 is not a GRB DATE: 15/03/12 10:03:19 GMT FROM: Dmitry Frederiks at Ioffe Institute D. Frederiks, on behalf of the Konus-Wind team, reports: The Konus-Wind trigger at 16:16:24.884 mentioned by Morii et al. (GCN 17568), which is 111 s before the MAXI trigger, is actually due to a X2.1 class solar flare. Therefore, taking into account the MAXI localization of the source, we suggest that the Maxi trigger is unrelated to the Konus-Wind trigger.
