The calculation results of parameters of thermal and dynamical processes in the near-Earth plasma during the partial solar eclipse of August 1, 2008, over Kharkov are presented. The calculations showed that during the eclipse there occurred a decrease in the neutral temperature by approximately 17–40 K within the height range 250–350 km, respectively. At heights of 210–580 km, the eclipse resulted in an increase in the density, total plasma flux, and the flux of particles by tens of percentage points due to ambipolar diffusion. The paper presents the results of a comparative analysis of the effects in the ionospheric plasma during the partial eclipses over Kharkov of August 11, 1999; May 31, 2003; October 3, 2005; March 29, 2006; and August 1, 2008. General regularities in eclipse effects are noted.
