At 03:28:08 UT 03 Nov 2011, Swift-BAT triggered as a result of the star tracker having lost lock. This trigger is not due to a GRB or anything astrophysical. Only one GCN Notice type (the Quick_Look type that goes to robotic telescopes) was distributed to the world. All the rest of the notice types were automatically blocked-to-world for Image triggers that occur during a period of star tracker...Full Text

At 13:40:41 UT, the Swift Burst Alert Telescope (BAT) re-triggered on what we are tentatively calling GRB 110328A (trigger=450161). The BAT on-board calculated location is consistent with the coordinates reported for GRB 110328A (GCN 11823; Cummings et al). Both this trigger and the earlier trigger (450158) were image triggers, so the light curves do not show any significant features. The current...Full Text
