GCN Circular 18610
S.Barthelmy (GSFC) on behalf of the Swift-BAT Team: Swift-BAT experienced a transient problem with thermal control of the detector array commencing at 16:30 UT 31-Oct-15 ((GCN Circ 18562). Thermal control was re-established and full triggering to GRBs and transients resumed at 17:05 UT 06-Nov-15. Survey and Monitor data were somewhat degraded due to elevated temperature of the CZT and reduced bias voltage. Normal temperature and full bias voltage were achieved at 14:23 UT 13-Nov-15, resulting in a full recovery to nominal BAT performance.
