Swift-XRT/UVOT observations of the new Galactic Transient Swift J185003.2-005627
Abstract
We have analysed 2.8 ks of Swift/XRT data from the new X-ray transient Swift J185003.2-005627 (Beardmore, et al., GCN Circ. 12083), from 88 s to 17.5 ks after the BAT trigger. The data comprise 421 s in Windowed Timing (WT) mode (the first 5 s were taken while Swift was slewing), with the remainder in Photon Counting (PC) mode.
The astrometrically corrected X-ray position for this source (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue), derived from 1660 s of XRT Photon Counting mode data and 2 UVOT images, is RA, Dec = 282.51390, -0.93980 which is equivalent to: RA (J2000): 18 50 3.33 Dec (J2000): -00 56 23.3 with an uncertainty of 1.7 arcsec (radius, 90% confidence).- Publication:
