SUMMARY OF THE EVENT: Ionospheric activity was observed above Europe during the 20th of April 2020 from 12:00 until 18:00 UTC. The Total Electron Content (TEC) was increased in average by 8 TECu at the peak 13:30 UTC. A maximum absolute TEC increase of 16 TECu (+92% with respect to the quiet condition) was estimated in the South, while maximum relative TEC increase of +154% (8.5 TECu) occurred “at mid latitude (55°)”. The next day, smaller increase of TEC up to 11 TECu were observed mostly in the Southern part.
