We observed the field of GRB 200519A (Sbarufatti et al. GCN 27756)
with the T31 0.5m telescope of iTelescope.Net in Siding Spring,
Australia. The observation was done with a luminance filter (400-700
nm) beginning at 2020-05-19 15:07:45 UT (about 3.8 hours after the
trigger) for 300 sec. The optical afterglow (Sbarufatti et al. GCN
27756) was detected with an estimated magnitude of 19.3+/-0.8 by
calibrating with the USNO UCAC5 catalogue.
