The TeV-detected HBL object of unknown redshift 1ES 0033+595 has been observed six times with X-ray Telecope onboard Swift satellite (Swift-XRT) since 2015 August 30 on the basis of our Target of Opportunity (ToO) requests of low and medium urgencies (see https://www.swift.psu.edu/secure/toop/summary.php). During this period, the source showed a permanent increase in the 0.3-10 keV count rate from 2.83+/-0.06 cts/s to 5.80+/-0.08 cts/s (superimposed with a minor fluctuation), and it is still sustaining a high X-ray brightness level during the last two Swift observations performed on Septemer 25 and 28. The lowest historical 0.3-10 count rate for 1ES 0033+595 is 1.58+/-0.05 cts/s while it reached the value of 9.24+/-0.14 ts/s in 2014 December during our another ToO observations. In the framework of one-zone SSC models, an increased activity is also expected in the radio-UV and gamma-ray parts of the spectrum, and intensive multiwavelength observations of 1ES 1959+650 are strongly encouraged to study instable processes and emission mechanisms in this source.
