IPN triangulation of GRB 200307A (short)
Abstract
The short-duration GRB 200307A (The Fermi GBM team, GCN Circ. 27344; Goldstein et al., GCN Circ. 27356) was detected by Fermi (GBM trigger 605309224), INTEGRAL (SPI-ACS), and Swift (BAT), at about 77219 s UT (21:26:59). The burst was outside the coded field of view of the BAT. We have triangulated this GRB to a GBM-INTEGRAL annulus centered at RA(2000)=81.577 deg (05h 26m 18s) Dec(2000)=-38.418 deg (-38d 25' 05"), whose radius is 32.263 +/- 3.868 deg (3 sigma). The IPN localization is consistent with, but reduces the area of, the joint Fermi-GBM/Swift-BAT one (GCN Circ. 27356). This localization may be improved.
