GCN Circular 10006
R. Margutti (INAF-OAB) & C. Guidorzi (U. Ferrara) report on behalf of the Swift XRT team: We have analyzed the first orbit data (1.8 ks exposure) of the Swift ToO observation of the SuperAGILE detected (Donnarumma et al., GCN Circ. 10004; Feroci, GCN Circ 10005) burst GRB 091010. The Swift observation started on 2009 Oct 10 at 14:48:26 UT, about 43 ks after the SuperAGILE trigger. We detected a single, uncatalogued X-ray source within the SuperAGILE error box at RA, Dec =298.6661, -22.5181 which is equivalent to: RA (J2000): 19h54m39.86s Dec (J2000): -22:31:05.2 with an uncertainty of 4.3 arcsec (radius, 90% confidence). The source lies 72 arcsec from the SuperAGILE position. The source has a count rate of about 5.7E-02 count s^-1. At the moment it is not possible to determine whether the source is fading given the current statistics. Burst Advocate for this burst is R. Margutti (raffaella.margutti AT brera.inaf.it). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/too.html.) This is an official product of the Swift-XRT team.
