report on behalf of a larger Italian collaboration:

A detailed reanalysis of our images (Fugazza et al., GCN 3078; D'Avanzo 
et al., GCN 3089) of the field of the Swift GRB 050306 (Markwardt et 
al., GCN 3071; Perri et al., GCN 3075) does not allow to confirm the 
variability of the candidate afterglow proposed in GCN 3089. At this 
stage, no afterglow detection for this burst can be claimed from our 
observations.
