IPN triangulation of GRB 201103B (consistent with ZTF20acozryr/AT2020yxz)
Abstract
The long-duration, bright GRB 201103B (AGILE detection: Ursi et al., GCN Circ. 28831) has been detected by AGILE, Konus-Wind, INTEGRAL (SPI-ACS), Mars-Odyssey (HEND), and Swift (BAT), so far, at about 65207 s UT (18:06:47). 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: 42.089 (02h 48m 21s) +12.441 (+12d 26' 29") Corners: 41.830 (02h 47m 19s) +14.128 (+14d 07' 41") 42.595 (02h 50m 23s) +11.069 (+11d 04' 07") 42.244 (02h 48m 59s) +10.759 (+10d 45' 32") 41.511 (02h 46m 03s) +13.781 (+13d 46' 52") --------------------------------------------- The error box area is 1.24 sq. deg, and its maximum dimension is 3.4 deg (the minimum one is 23.8 arcmin). The Sun distance was 175 deg. This box may be improved. The distance between the optical transient ZTF20acozryr/AT2020yxz (Coughlin et al., GCN Circ. 28841) and the IPN box center is 19 arcmin, thus confirming the association of the burst and the OT. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB201103_T65207/IPN The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.- Publication:
