Tohuvavohu\non behalf of the Swift-BAT team, report:\n\nThe long-duration GRB 220219B\nhas been detected by Konus-Wind (KW) and Swift (BAT), so far,\nat about 34045 s UT (09:27:25).\nThe burst was outside the coded field of view of the BAT.\n\nWe have triangulated it to a Konus-BAT annulus centered at\nRA(2000)=314.433 deg (20h 57m 44s) Dec(2000)=-14.987 deg (-14d 59' 15\"),\nwhose radius is 83.789 +/- 1.439 deg (3 sigma).\n\nThis localization may be improved.\n\nThe position of the optical transient ZTF22aabjpxh/AT2022cva\n(Ho et al., GCN Circ. 31619) is inside the annulus at 0.46 deg\nfrom its center line. The OT position is consistent with the Swift-BAT \ndetection, Fermi-GBM non-detection, and the KW ecliptic latitude response.\n\nThe positional and temporal coincidence of this burst with the OT \nsupports the conclusion that the OT is the GRB counterpart.\n\nA triangulation map is posted at\nhttp://www.ioffe.ru/LEA/GRBs/GRB220219_T34045/IPN\n\nThe time history and spectrum will be given in forthcoming GCN Circulars.",
