report on behalf of the Swift-XRT team:
Swift-XRT has performed follow-up observations of the MAXI-detected
burst GRB 190823A (Iwakiri et al. GCN circ. 25456) in a series of
observations tiled on the sky.
Total exposure time is 1.8 ks, distributed over 7 tiles. The data were
collected
between T0+12.1 ks and T0+18 ks.
One uncatalogued X-ray source has been detected, with the following details:
RA (J2000.0): 279.68736d = 18:38:44.97
Dec (J2000.0): -43.52789d = -43:31:40.4
Error: 8.6 arcsec (radius, 90% conf.)
Count-rate: 4.1 (+1.7, -1.3) ��10^-2 ct s^ -1
Distance: 18.6 arcmin from MAXI position
The results of the XRT-team automatic analysis of the tiled XRT
observations, including a position-specific upper limit calculator, are
available at https://www.swift.ac.uk/xrt_products/TILED_GRB00085/ .
This circular is an official product of the Swift-XRT team.
