AbstractThe long-duration GRB 200120A (The Fermi GBM team, GCN Circ. 26831; Insight-HXMT/HE detection: Zheng et al., GCN Circ. 26840; AstroSat CZTI detection: Gaikwad et al., GCN Circ. 26851) was detected by Konus-Wind, Fermi (GBM trigger 601254300), INTEGRAL (SPI-ACS), Mars-Odyssey (HEND), Insight (HXMT/HE), AstroSat (CZTI), and Swift (BAT) at about 83095 s UT (23:04:55). The burst was outside the coded field of view of the BAT. We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 137.180 (09h 08m 43s) -70.389 (-70d 23' 22") Corners: 136.684 (09h 06m 44s) -70.872 (-70d 52' 19") 136.099 (09h 04m 24s) -70.854 (-70d 51' 15") 137.657 (09h 10m 38s) -69.906 (-69d 54' 21") 138.218 (09h 12m 52s) -69.919 (-69d 55' 08") --------------------------------------------- The error box area is 686 sq. arcmin, and its maximum dimension is 1.2 deg (the minimum one is 10.6 arcmin). The Sun distance was 88 deg. This box may be improved. The IPN localization is consistent with, but reduces the area of, the Fermi-GBM (GCN Circ. 26831) and BALROG (https://grb.mpe.mpg.de/grb/GRB200120962) one. This event is spatially and temporally inconsistent with the IceCube 200120A neutrino candidate event (GCN Circ. 26832). A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB200120_T83096/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
