TITLE: GCN CIRCULAR NUMBER: 17610 SUBJECT: Swift Triggers 635788-635794 are probably not real. DATE: 15/03/22 09:12:12 GMT FROM: Phil Evans at U of Leicester P. A. Evans (U Leicester), N. P. M. Kuin (UCL-MSSL), A. Y. Lien (GSFC/UMBC), C. J. Mountford (U Leicester) and P. Romano (INAF-IASFPA) report on behalf of the Swift Team: Between 08:10:02 UT and 09:03:38 UT Swift reported 5 triggers, all of which were 64-s image triggers. Trigger 635788 which was identified as possibly being on the known source GRS 1915+105 and the rest (635789, 635790, 635792, 635794) on unknown sources. All of these triggers occurred while the star trackers had lost lock. Prompt images show that Swift was not stationary while taking these observations. We believe therefore that these are spurious triggers and are not astrophysical, however until we get the full ground dataset we are unable to say this for certain.
