We observed the NIR afterglow of GRB 210619B (D'Avanzo et al., GCN Circ. 30261) with the Italian 3.6m TNG
telescope equipped with the near-infrared camera NICS. A series of images were obtained with the J and K filters
on 2021-06-21 from 01:27:06 UT to 02:49:36 UT (i.e. at a mid time of about 1.09 days after the burst).
With preliminary photometry we derive the following magnitudes:
J = 17.90 +/- 0.05
K = 16.43 +/- 0.11
(Vega; calibrated against the 2MASS catalogue).
