D. A. Kann (HETH/IAA-CSIC), A. de Ugarte Postigo (HETH/IAA-CSIC, 
DARK/NBI), M. Blazek, L. Izzo (both HETH/IAA-CSIC), A. Guijarro Roman, 
A. Fernandez Martin (both CAHA), C. C. Thoene, K. Bensch (both 
HETH/IAA-CSIC), report:

We observed the enhanced XRT position (Evans et al., GCN #23903) of 
Swift GRB 190219A (Beardmore et al., GCN #23902) with the 2.2m telescope 
of CAHA equipped with CAFOS. We obtained 3 x 180 s images in the Ic band 
under inclement weather conditions and the influence of the full Moon.

At the XRT position, we do not detect any source down to Ic > 21.5 mag 
(AB mag) at 0.038627 days after the GRB trigger, calibrated against 
nearby PanSTARRS objects. No source is visible at this position in 
PanSTARRS imaging either. This non-detection is in agreement with 
Beardmore et al. (GCN #23902) and Perez del Pulgar et al. (GCN #23904).
