Swift observations of Swift J1843.5-0343
Abstract
The binary pulsar system Swift J1843.5-0343 (Krimm et al, ATel #3109; Strohmayer & Markwardt, ATel #3121) was observed with Swift starting at 2011 Feb 15 00:27:25 UT for 1.9 ksec in PC mode and starting at 2011 Feb 15 03:46:37 for 2.0 ksec in WT mode. A point source was found in the Swift/XRT at at the astrometrically corrected (utilizing the method of Evans et al, 2009, MNRAS, 397, 1177) location: RA (J2000): 18 43 34.75 (280.89481 deg)
Dec (J2000): -03 42 56.6 (-3.71571 deg)
90% Error radius: 2.7" The faintness of the source (mean of 0.038 ± 0.024 cts/s in 0.3-10 keV) makes spectral fitting difficult.
