We observed Fermi GRB 190530A (Fermi GBM Team, GCN Circ. 24676;
Longo et al., GCN Circ. 24679) using the Xinglong-2.16m equipped with
the BFOSC camera. Observations were carried out from 12:49:45 to
13:40:10 UT on 2019-05-31, 62*50sec R band images were obtained.
The optical afterglow (Lipunov et al., GCN 24680, 24693; Kann et al., GCN Circ 24684;
Melandri et al., GCN Circ. 24689; Heintz et al., GCN Circ 24686; Lzzo et al., GCN Circ 24687;
Xin et al., GCN Circ 24688; Watson et al., GCN Circ.24690) was clearly detected in our
stacked image with a magnitude of R=19.63+/-0.1 mag at the mid time of about 1.12 days
after the burst, calibrated with nearby SDSS stars
