report:

The short-duration GRB 200514B
(Fermi-GBM detection: The Fermi GBM team, GCN Circ. 27736;
BALROG localization: Burgess et al., GCN Circ. 27748)
was detected by Fermi (GBM trigger 606799116),
INTEGRAL (SPI-ACS), and Konus-Wind in the waiting mode,
at about 32857 s UT (09:07:37).

We have triangulated it to a Konus-GBM annulus centerd at
RA(2000)=233.253 deg (15h 33m 01s) Dec(2000)=-18.040 deg (-18d 02' 24"),
whose radius is 79.909 +/- 20.599 deg (3 sigma), and
to a GBM-INTEGRAL annulus centered at
RA(2000)=209.576 deg (13h 58m 18s) Dec(2000)=+50.867 deg (+50d 52' 01"),
whose radius is 33.883 +/- 33.883 deg (3 sigma).

The IPN localization is consistent with, but reduces the area of
the Fermi-GBM ones (GCN 27736, GCN 27748).

This localization may be improved.
