Vergani, F. Vitali report on behalf of the REM team: The REM 60-cm robotic telescope located at ESO-La Silla reacted promptly after the Swift alert for GRB09094B. Observations began 108 seconds after the GRB time (40 s after the trigger) with the R and H bands and continued with all the available filters (VRIJHK). No transient was singled out in the images, although a not varying 2MASS star with H=11.95 seems to be coincident with the XRT position. The field is located very close to the Galactic Center (LII = 2.12 deg, BII = 3.64 deg) and is heavily reddened and crowded, requiring further analyses to evaluate the chance for this positional coincidence. Further observations are in progress. ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/
