GCN Circular 23997
M. Perri (ASDC), G. Tagliaferri (INAF-OAB), P.A. Evans (U. Leicester), J.P. Osborne (U. Leicester), D.N. Burrows (PSU) and J.A. Kennea (PSU) report on behalf of the Swift-XRT team: The XRT began observing the field of GRB 190324A at 23:38:59.4 UT, 3297.9 seconds after the BAT trigger. Using promptly downlinked data we find an uncatalogued X-ray source located at RA, Dec 49.62054, -47.21240 which is equivalent to: RA(J2000) = 03h 18m 28.93s Dec(J2000) = -47d 12' 44.6" with an uncertainty of 3.7 arcseconds (radius, 90% containment). This location is 145 arcseconds from the BAT onboard position, within the BAT error circle. This position may be improved as more data are received; the latest position is available at http://www.swift.ac.uk/sper. A power-law fit to a spectrum formed from promptly downlinked event data gives a column density in excess of the Galactic value (1.75 x 10^20 cm^-2, Willingale et al. 2013), with an excess column of 7 (+3.19/-2.76) x 10^21 cm^-2 (90% confidence).
