The magnetospheric response by means of Kp and Dst was similar in both events. Within the ionospheric parameters selected foF2 and h'F were selected. The HSS event was followed by a significant decrease in foF2 values in the duration of 2 days. No change was observed for night foF2 in this case.The response to the CME was much weaker than to the HSS and less change in foF2 was observed. Both events were followed by h'F oscillations which may indicate Travelling Ionospheric Disturbances (TID).
