Maselli (INAF-IASFPA), T. Sakamoto (AGU) and M. \nH. Siegel (PSU) report on behalf of the Swift Team:\n\nSwift has gathered 5.8 ks of WT mode data and 463 s of PC mode data on \nthe field of the BAT trigger 700791 (= possible GRB 160622A, GCN 19547).\n\nThe XRT image is dominated by diffuse emission from the supernova \nremnant RCW 103 (Frank et al., ApJ, 2015, 810,113), with a bright \ncentral source at RA,Dec. = 244.40282,  -51.03916,  which is equivalent to:\n\nRA (J2000.0) = 16h 17m 36.68s\nDec (J2000.0) = -51d 02' 21.0\"\n\nwith an uncertainty of 3.5\" (radius, 90% confidence). This is consistent \nwith the catalogued X-ray source 3XMM J161736.1-510224. Analysis is \ncomplicated by the presence of the diffuse emission from the SNR, \nhowever the source count rate is ~2 ct/sec, with a flux of approximately \n9.1 (+2.0, -1.6) �� 10^-11 erg cm^-2 s^-1 (derived from a power-law \nspectrum with NH=7.0 (+3.6, -2.5)e21 cm^-2, and a photon index of 2.2 \n(+/- 0.4). This is substantially above the 3XMM count rate of 2.567 (+/- \n0.020)e-12 erg cm^-2 s^-1.\n\nObservations and analysis are ongoing.\n\nThis circular is an official product of the Swift XRT team.\n\n[GCN OPS NOTE(22jun16): Per author's request, A.D'A's name was corrected,\nand the missing minus sign for the sexagesimal form of the Dec value\nwas added.]",
