We propose INTEGRAL observations of the accreting binary X-ray pulsar Her X-1 for a total of 690 ks in its Main-On state. Principal goals includeinvestigation of the hard X-ray profile evolution with the phase of the 35-day cycle (JEMXIBIS) and cyclotron line spectroscopy (SPI). Secondary task is the INTEGRAL monitoring of known and search for new sources in the Her X-1 field as a part of hard X-ray survey of unexplored extragalactic fields. [truncated!
