We performed the search for the optical counterpart of LIGO/Virgo 
S190510g (LVC, GCN 24442) using the Half-Meter Telescope (HMT) located 
at Dabancheng, Xinjiang, China. Observations started at 16:00:00 UT on 
2019-05-10 and ended at 22:32:00 UT on 2019-05-10, and the 60x40 
arcmin^2 unfiltered imager scanned relatively high probability regions 
of the LVC localization that are accessible to HMT.

The total area is about 97 deg^2, and listed below are the field centers 
observed.

Data analysis is ongoing. Optical transients from the above fields, if 
interesting, will be reported later.
