On 2002 April 7.14 we observed the optical counterpart of GRB 020405
reported by Price et al. (GCN 1326). The observations were performed
with the ESO VLT-3 (Melipal) telescope equipped with FORS1 with a V
filter in the imaging polarimetry mode. The transient source is clearly
detected and the acquisition image allowed to derive the Bessel V
magnitude of the transient, V=21.45 +/- 0.1, assuming V=18.5 and V=17.6
for the comparison USNO-A2.0 stars 0525-16813005 and 0525-16815468,
respectively, as reported in Palazzi et al. (GCN 1328).
