"We observed the field of the GRB 070802 (S. D. Barthelmy et al., GCN 
6692)  with the robotic 60-cm REM telescope located at La Silla (Chile).
A set of observations was performed automatically in the R optical filter 
starting at 07:17:44 UT (52 sec after the Swift alert; about 10 minutes 
after the burst) and lasted about 40 minutes.

The analysis of the first 15 minutes exposures do not show 
the optical/NIR afterglow candidate reported by J. Greiner et al (GCN 
6694), E. Berger et al (GCN. 6695), D. Malesani et al (GCN. 6696). 
The 3-sigma limiting magnitude in the stacked images is R~17.0"
