Murison, U.S. Naval Observatory--Flagstaff Station (NOFS)\n\nWe imaged the position of the reported Swift/UVOT transient (Breeveld\net al., GCN Circ. 24296), potentially corresponding to LIGO/Virgo trigger\nS190425z (LIGO/Virgo Collaboration, GCN Circ. 24168), with the NOFS\n1.3-meter telescope. Nine 900-second exposures were taken in SDSS r (5)\nand g (4). Examination and comparison to PS1 reveals no new sources\nbrighter than apparent SDSS r magnitude 22.3. Exposure times were\n2019-04-28 08:44 to 11:12 UTC. Stacking images did not produce benefit\ndue to variable and worsening seeing.",
