We observed the afterglow of GRB 190211A(Marshall et al., GCN 23883; Xu et
al., GCN 23884; Lipunov et al., GCN 23885; Hu et al., GCN 23886; Stamatikos
et al., GCN 23887; Evans et al., GCN 23888) with the 1.0-m telescope at the
Deokheung Optical Astronomy Observatory.
The observation started at 2019-02-11 18:28 UT or about 1.5 hours after the
initial alert.
The afterglow is detected in R bands, and preliminary magnitudes are
derived, using nearby Pan-STARRS stars as photometry references.
