report on behalf of the Neil Gehrels Swift Observatory Team:
At 05:57:29 UT, the Swift Burst Alert Telescope (BAT) possibly triggered and
located PSR B1055-52 (trigger=896552). Swift did not slew due to the low merit
value of this trigger. The BAT on-board calculated location is
RA, Dec 164.407, -52.387, which is
RA(J2000) = 10h 57m 38s
Dec(J2000) = -52d 23' 12"
with an uncertainty of 3 arcmin (radius, 90% containment, including
systematic uncertainty). As is typical for image triggers, there is nothing
visible in the light curve.
Due to the low image significance and the distance to the PSR_B1055-52 source
(~5 arcmin) this identification of this trigger is not strong. The proper
identification will require the full data set.
This source lies within the current (Sector 10) field-of-view of TESS camera 2.
