P. D'Avanzo (INAF-OABr), S. Piranomonte, L. Stella (INAF-OAR) and G.
Chincarini ((INAF-OABr) report on behalf of the MISTICI collaboration:

We observed the field of the short GRB 070707 (Beckmann et al., GCN
6605; Gotz et al., GCN 6607) using FORS1 on the VLT telescope about 11
hours after the trigger time. We obtained 20 minutes of R-band imaging.

Inside the refined INTEGRAL error circle (Gotz et al., GCN 6607) we do
not detect any obvious afterglow candidate down to the depth of the
DSS image. Our 3-sigma limiting magnitude is R=25.7.

Further observations are planned. We acknowledge the ESO staff for
reliable support.
