Ionospheric response to geomagnetic storm and solar eclipse during March
Original language description
We show results from ionospheric measurement at the Pruhonice station,nCzech Republic, for the Solar Eclipse 20 March 2015 (SE). The DPS-4DnDigisonde, continous Doppler measurement and wave analysis of electronndensity profiles were used to describe response of the ionosphere. Thenvariability in plasma drifts and critical frequencies exists before the SEnand can be attributed to the geomagnetically disturbed situation. Decreasenin solar ionization flux during the SE leads to decrease in criticalnfrequencies from the E, F1 and F2 layers with a delayed response for thenF2 region. The results from Digisonde Doppler measurement show variationsnin velocity in the F2 region plasma compared to average situation fromnother days of the same season, reaching -100 to +100 m/s in horizontal,nand -30 to +30 m/s in vertical components. Continuous Doppler driftnmeasurement detect dominant south-east direction of the wave propagation.nAnalysis of electron density profiles shows increased wave activity afternthe SE in the domain of gravity waves.
