Hagen (PSU) reports on behalf of the Swift/UVOT team:\n\nUVOT took a finding chart exposure of 150 seconds with the White filter\nstarting 3998 seconds after the BAT trigger (Hagen et al., GCN Circ.\n19684). No credible afterglow candidate has been found in the initial\ndata products. The 2.7'x2.7' sub-image covers 100% of the XRT error\ncircle (Kennea et al., GCN Circ. 19686). The typical 3-sigma upper limit\nhas been about 19.6 mag. The 8'x8' region for the list of sources\ngenerated on-board covers 100% of the XRT error circle. The list of\nsources is typically complete to about 18 mag. No correction has been\nmade for the expected extinction corresponding to E(B-V) of 0.08.",
