  In this paper, the long-term historical optical (UBVRI) and near-infrared
(JHK) data are presented with some new observations in the optical (February
1994-January 1995) and near-infrared (November 1995) bands included for BL Lac
object OJ287. The new optical data in V-band are in agreement with the results
reported by other authors (Sillanpaa et al. 1996a; Arimoto et al. 1997), a
close correlation between the color index of B-V and the magnitude V has been
obtained from our new observations; The new infrared observations presented
here indicate that the source was at a high level in the infrared band during
the observation period;
  From the available literature, we have got that the largest variations for
UBVRIJHK bands are respectively: 4.72mag, 5.93mag, 5.18mag, 4.45mag, 4.07mag,
3.87mag, 3.78mag, and 3.54mag. A strong correlation is found between the
optical and near-infrared bands when the DCF method is used, which suggests
that these two bands have the same emission mechanism.
