Z.P. Zhu, D. Xu, B.Y. Yu (NAOC), J.H. Liu (XAO) report:
We observed the field of GRB 190219A (Beardmore et al., GCN 23902) using
the NEXT-0.6m telescope located at Nanshan, Xinjiang, China. We obtained
10x90s frames in the R filter, started at 19:57:52 UT on 2019-02-19,
i.e., 18.43 min after the burst.
No optical source is detected at the XRT position (Beardmore et al., GCN
23902 & 23907) in our stacked image, down to a 3 sigma limiting
magnitude of R~17.5.
