  The variability of the X-ray flux from the pulsar GX 301-2 is analyzed by
using data from the ART-P telescope of the Granat Observatory. The intensity
variations with time scales of several thousand seconds are studied at various
orbital phases. The high-state flux from the source exceeds its low-state flux
by as much as a factor of 10. The hardness and spectrum of the source are shown
to change greatly with its intensity. These intensity variations are most
likely caused by substantial inhomogeneities in the stellar wind from the
companion star.
