report:
"Following the detection by INTEGRAL of GRB 050520
(Gotz et al. GCN Circ. 3430), we have taken images
in the VRI bands with the 1.5m telescope at IAA's
Observatorio de Sierra Nevada, starting at 00:39 UT
(i.e. 30 minutes after the event). The co-add of
the first three I-band frames (3 x 300 s exposure
time) reveals no optical counterpart in the 1.5'
radius error box down to the DSS2 limiting magnitude.
Further analysis is ongoing."
