on behalf of the Swift-BAT team, report:

The short-duration GRB 230712C
was detected by Fermi (GBM), Konus-Wind, Swift (BAT), and
INTEGRAL (SPI-ACS) at about 2575 s UT (00:42:55).
The burst was detected by Fermi (GBM) during
the trigger record of GRB 230712A (Fermi/GBM trigger 710815158).
The burst occurred during Swift slewing interval
(when normal BAT triggering is disabled).

We have triangulated it to a Konus-SPI-ACS annulus centered at
RA(2000)=110.347 deg (07h 21m 23s) Dec(2000)=+22.378 deg (+22d 22' 41"),
whose radius is 65.487 +/- 17.400 deg (3 sigma).

The annulus combined with the Fermi-GBM position gives 3749 sq. deg (3 sigma) localization region.
