report:
We observed the field of GRB 050820A (Page et al., GCN 3830) in the NIR
at the TNG equipped with NICS on the 21st of August at 05:00 UT, about
22.4 hours after the high-energy event. The OT identified by Fox et al.
(GCN 3829) is clearly visible with J magnitude:
J = 18.48 +/- 0.08
Calibration has been derived by comparison with a suitable number of
2MASS stars in the field.
