Stamatikos (OSU/NASA/GSFC) and T. N. Ukwatta (GSFC/GWU) report on\nbehalf of the Swift Team:\n\nAt 06:18:20 UT, the Swift Burst Alert Telescope (BAT) located \ntrigger 422437.  Swift slewed immediately to the location. \nThe BAT on-board calculated location is RA, Dec 311.162, +40.170 which is \n   RA(J2000) = 20h 44m 39s\n   Dec(J2000) = +40d 10' 12\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The raw light curve showed a rise of count\nrate as the spacecraft passed into the South Atlantic Anomaly (SAA). \n\nThe XRT began observing the field at 06:19:41.1 UT, 80.3 seconds after\nthe BAT trigger. No source was detected in the promptly available XRT\ndata. We are waiting for the full dataset to detect and localise the\nXRT counterpart. \n\nDue to the passage through the SAA at the time of  the trigger, no\nUVOT data is available at this time. \n\nDue to the effect of the SAA, the marginal detection (6.6 sigma)\nin the BAT image, and the lack of a detection in the XRT,\nwe believe that this is probably not an astrophysical event. \nFurther determination of the reality of this object will\nrequire the downlinked Malindi data. \n\nBurst Advocate for this burst is J. L. Racusin (judith.racusin AT nasa.gov). \nPlease contact the BA by email if you require additional information\nregarding Swift followup of this burst. In extremely urgent cases, after\ntrying the Burst Advocate, you can contact the Swift PI by phone (see\nSwift TOO web site for information: http://www.swift.psu.edu/too.html.)",
