Based on the optical studies, the blazar OJ 287 has been proposed as a binary black hole system, thus making it an interesting source to study further.
In this work, we analyzed the optical, UV, X-ray, and $\gamma$-ray data of the source spanning a period from 2017 -- 2020. According to the observed variability in optical and X-rays, this period is divided into five segments, namely, A, B, C, D, and E. To understand the nature of temporal variability, we studied intraday variability and estimated fractional variability for above mentioned five states. Also, we modeled the multiwavelength spectral energy distribution (SED) to have a better understanding of simultaneous broadband emission. The blazar OJ 287 was found to be in a high state and displayed significant flux variability in optical, UV, and X-rays during the period in the study. In contrast, Fermi-LAT shows moderate flux variations during this time period. Finally, a single-zone synchrotron self-Compton (SSC) emission model is found to best explain the nature of the blazar OJ 287.
