report:
We have taken R-band frames covering the error box
for the long-lasting XRF 040916 detected by HETE-2
(Yamazaki et al., GCN Circ. 2712; Yamamoto et al.
GCN Circ. 2713). A set of five images (300-s exposure
time each) was taken at the 2.5m INT (+WFC) on
La Palma during the time interval 16 Sep (02:50 UT -
04:06 UT, i.e. 2.87-4.05 hr after the burst). No new or
strongly variable object is found in the entire error box
down to R = 21, when comparing with the DSS-2 red.
