Description
1ES 1959+650 is a well known HBL with its synchrotron peak lying in soft X-ray band (0.3-10.0keV). It is also observed that the peak position of synchrotron component changes significantly with the brightness state of this blazar. This source underwent first major TeV activity in 2015 after a long silence in VHE bands. We have compiled all the multi-wavelength data between 2015 to 2021 accumulated over almost entire energy spectrum. A rigorous spectral and temporal investigation is performed to understand the detailed nature of the variability observed over the years. We plan to provide a detailed presentation of the findings during the conference.
