GCN Circular 10515
L. Vetere (PSU), S. D. Barthelmy (GSFC), W. H. Baumgartner (GSFC/UMBC), C. B. Markwardt (CRESST/GSFC/UMD), F. E. Marshall (NASA/GSFC), D. M. Palmer (LANL), M. H. Siegel (PSU) and T. N. Ukwatta (GSFC/GWU) report on behalf of the Swift Team: At 04:43:54 UT, the Swift Burst Alert Telescope (BAT) image triggered (#416226). Swift slewed immediately to the location. Due to the non-detection of a source in the XRT and UVOT images, and the marginal image significance (7.0 sigma) in the BAT, we think this is probably not a GRB. Further determination of the reality of this burst will require the analysis of the Malindi data.
