1ES 1959+650 is one of the X-ray bright blazars and a frequent target of various space missions and ground-based telescopes. In the framework of our intensive studies, the source has shown an 0.3-10 keV flux variability on diverse timescales from a few months down to the fluctuations over several hundred seconds. Since 2015 August, it is exhibiting a period of enhanced X-ray activity. Being regularly monitored with different Cherenkov-type telescopes, 1ES 1959+650 has been frequently detected at very high-energy frequencies and exhibited an uncorrelated X-ray--TeV variability several times. In this paper, we give a short review of the results of multiwavelength studies of this object performed by various authors to date.
