Abstract :
The ionosphere modification at mid-latitudes caused by the solar eclipse on January 4, 2011 is consider. The observations of ionosphere were carried out with digital ionosonde “Parus” and dual frequency GPS/GLONASS receiver. In order to analyze the spatial and temporal changes of the ionosphere over Europe the GNSS network data was used. The eclipse was observed from 7.17 till 10.05 UT. The maximal phase of eclipse was registered at 8.39 UT with the coefficient of Solar disk covering of 76.94%. The eclipse over observation point took place at aftersunrise hours. The negative effect in foF2 values and TEC distribution was clearly observed. The foF2 decrease up to 1.6 times was registered with delay of about 10 min relative to the maximum eclipse phase. The observation results are presented.
