Malesani (DARK/NBI), V. D'Elia (INAF/OAR and ASI/ASDC), P. D'Avanzo (INAF/OABr), A. Melandri (INAF/OABr), S. Covino (INAF/OABr), V. Lorenzi (INAF/TNG), Albar Garcia de Gurtubai Escudero (INAF/TNG), report on behalf of the CIBO collaboration: We observed the field of GRB 150222A (Bernardini et al., GCN 17486) with the 3.6m TNG telescope equipped with the DOLoRes camera. Observations consisted of 4 images in the I band for a total of 20 min exposure. The seeing was poor (3.2"). No object is detected within the (currently unenhanced) XRT position, down to a limiting magnitude I > 22.3 (calibrated against nearby USNO stars). The mean time of the observation was 2015 Feb 23.055 UT, that is 8.4 hr after the GRB.
