collaboration:
We performed the search for the optical counterpart of LIGO/Virgo
S190408an (Singer et al. GCN 24069) using the Half-Meter Telescope (HMT)
located at Dabancheng, Xinjiang, China. Observations started at 13:50:00
UT on 2019-04-09 and ended at 22:43:00 UT on 2019-04-09, and the 60x40
arcmin^2 unfiltered imager scanned the highest probability regions of
the LVC localization that are accessible to HMT.
The total area is about 48 deg^2, and listed below are the field centers
observed.
