We report the search results in the BAT data within T0 +/- 100 s of the
LVC event S191129u (LIGO/VIRGO Collaboration GCN Circ. 26303),
where T0 is the LVC trigger time (2019-11-29T13:40:29.197 UTC).

The center of the BAT field of view (FOV) at T0 is
RA = 270.454 deg,
DEC = 18.713 deg,
and the roll angle is 210.645 deg.
The BAT FOV (>10% partial coding) covers 10.00% of the integrated
LVC localization probability, and 10.12% of the galaxy convolved
probability (Evans et al. 2016).

BAT was in SAA from T0-786 s to T0+352 s. Therefore, BAT data
analyses are unavailable around T0.

The results of the BAT analysis are available at
