Observations of Ultrawideband Signals in GPS TEC Variations Over Europe During Solar Eclipse

We present the results of comparative analysis of ultrawideband signals observed in TEC variations over Europe during the solar eclipse of 20 March 2015. Wave disturbances over a number of European cities are detected which have periods of 50 - 60 min and durations of 120 - 180 min. Their amplitudes are of 0.8 - 2 TECU and exhibit positive correlation with Hurst exponent values. The fractional bandwidth is of 0.67 - 1.14 for all analyzed signals. Obtained results agree closely with those from incoherent scatter and vertical sounding techniques.
