P. A. Evans (U Leicester), C. Gronwall (PSU), R. Gupta (NASA GSFC), A. Y. Lien (U Tampa) and K. L. Page (U Leicester) report on behalf of the Neil Gehrels Swift Observatory Team: BAT trigger 1500148 is not a GRB, but was caused by a solar flare. Swift's automatic slews are currently disabled, so there will be no XRT or UVOT data for this trigger.
