1 Otero, Sebastian Alberto J-K= 1.98. Light curve and colour suggest a carbon mira. The star is not included in the OGLE catalogue because it is too bright in the Ic-band. The analysis was made on the contaminated light of the artifact OGLE BUL-SC25 207161 and the magnitudes were corrected using the contemporaneous DENIS Ic observation.
