Анотація: The thermal structure and dynamical processes that occurred in the thermosphere-ionosphere system during the 3 October 2005 partial (24 %) solar eclipse are modeled. The solar eclipse is shown to cause an significant increase in the plasma fluxes in the 340‒410 km altitude range, respectively, a decrease of 5‒15 К in the neutral temperature in the 300‒360 km altitude range, a decrease of 40‒20 % in the energy inputs to the electron gas in the 290‒340 km altitude range, and a decrease of 17‒13 % in the electron heat flow in the same 290‒340 km altitude range. The effects which were observed in the thermosphere-ionosphere system near Kharkiv during the 11 August 1999, 31 May 2003, 3 October 2005, and 29 March 2006 solar eclipses are compared.
