During March 2015 two significant events strongly disturbed the state of the ionosphere
over Central Europe. Strong geomagnetic storm with Kp - 8 and DST - 223 started 17.3.2015.
During the recovery phase of this storm the second significant event Solar eclipse 20.3.2015
strongly affected the state of the ionosphere above Europe.
Paper presents changes of the state of the ionosphere observed during geomagnetic storm
17.3.2015 and Solar eclipse 20.3.2015 as was observed at ionospheric observatory Pruhonice.
Digisonde DPS4 D, installed at the Pruhonice observatory, allow standard ionospheric
vertical sounding measurements. Digisonde DPS4 D is also working as Doppler radar and allow
ionospheric drift measurements. Ionospheric vertical sounding and drift velocity was measured
with standard delay time 15 minutes during geomagnetic storm. Solar eclipse 20.3.2015 above
Pruhonice started 08:36 UT and finished 10:45 UT with magnitude 0.743.
Ionospheric vertical sounding data and drift velocity measurements with delay time 3
minutes was measured during eclipse event. Tis time resolution allow observation short time
changes of the inosphere during eclipse event.
