GCN Circular 32887
S. Dichiara (PSU), J. A. Kennea (PSU) and A. Y. Lien (U Tampa) report on behalf of the Neil Gehrels Swift Observatory Team: At 06:48:50 UT, the Swift Burst Alert Telescope (BAT) triggered (trigger #1132968) that was identified as Crab. However, the BAT transient monitor does not show any significant activity of the Crab. Also, this trigger is a 12.7-min long image trigger, similar to the condition of previous erroneous triggers due to a known race condition in the Swift/BAT software. Therefore, we believe this trigger is not due to interesting activity of the Crab. The full ground data is required to confirm the nature of this trigger. The XRT began observing the field at 12:23:53.1 UT, 1087.3 seconds after the BAT trigger. XRT's onboard centroiding algorithm did not find a point source in the field of view, however as the Crab is an extended source, this is as expected.
