Marshall (NASA/GSFC)\nreport on behalf of the Swift/UVOT Team:\n\nPreliminary UVOT photometry of the afterglow of GRB 080721 (Marshall,\net al. 2008, GCN Circ. 7988) shows that the afterglow is strongly\ndetected in the U band, but not in the UVW1, UVM2, or UVW2 bands at\napproximately 825 s after the BAT trigger.  This suggests that the\nredshift of GRB 080721 may be greater than approximately 2.3.",
