srclist paragraph message for exposure 2 of trigger 895503
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.

------ Start for Possible Stand-alone Circular ----
In response to GRB190327 (Swift/BAT trigger 895503) at 23:16:13 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of nominal 250.000 seconds with the U filter
starting 281 seconds after the BAT trigger. No credible afterglow candidate has
been found in the initial data products. Data from the 2.7'x2.7' sub-image are
not available at this time. The 8'x8' region for the list of sources generated
on-board covers 100% of the BAT error circle. The limiting magnitude for the
list of sources is expected to be about 17.7. No correction has been made for
the expected extinction corresponding to E(B-V) of 0.25.
