Meurs, P. Goldoni, on behalf of the REM/ROSS Team report: 


Following the detection of a candidate optical counterpart for XRF
050509c (HETE trigger #3751; GCN 3402), by Gorosabel et al. (GCN 3425)
we re-analyzed our optical and NIR REM data (D'Avanzo et al GCN 3400).
At 2.5 hours after the burst no object is found at the position of the
candidate down to a limiting magnitude of R=19 and H=15.5 (3-sigma
level). We note that our R limit is consistent with a power-law decay
index of -1.2 (Gorosabel et al. GCN 3425).
