The variability characteristics of the OJ 287 database.The authors present preliminary results of the study of short-term variability of the BL Lac object OJ 287. There is evidence that the variability amplitude of OJ287 is greater when it is brighter.González-Pérez, J. N. et al.

The UV - optical - near-IR emission of BL Lacertae objects.Results from UV, optical and near-IR simultaneous observations for 11 BL Lac objects are reported. The authors find that for all but one source the spectral flux distribution can be described by a single power law (fν ∝ ν-α) plus, where relevant, the contribution of the host galaxy. The comparison of the optical-near-IR and UV spectral indices forFalomo, R. et al.

The optical, infrared and radio light curve of OJ 287 during winter 1993 - 94.The light curves of OJ 287 at UBVRIJHK, 22 and 37 GHz are presented for the 1993/94 observing campaign. Despite the considerable optical and infrared activity the light curve at 22 and 37 GHz is quite inactive. A slow increase in the flux is evident at both radio frequencies from the end of 1993, but this is much smaller than the visibleKidger, M. et al.
