  We present the results of a temporal and spectral study of the BL Lacertae
object OJ 287 in optical, UV, and X-ray bands with observations performed by
Swift satellite during September 2019--March 2020. In this period, the source
showed moderate variability characterized by variability amplitude of
$\sim$22--31% in all the wavelengths on a short timescale, except the hard
X-ray band which was variable by only $\sim$8%. We observed that the X-ray flux
of the source was significantly dominated by the soft photons below $2$ keV.
Soft lags of $\sim$45 days were detected between the optical/UV and soft X-ray
emissions, while there is no correlation between the hard X-rays and the lower
energy bands indicating the presence of two emission components or electron
populations. Although two components contribute to the X-ray emission, most of
the 0.3--10 keV spectra were well fitted with an absorbed power-law model which
outlines the dominance of synchrotron over inverse Compton (IC) mechanism. The
X-ray spectra follow a weak "softer when brighter" trend.
