Sporadic E propagation is a summer phenomenon where ionized patches in the E-layer of the ionosphere create short-distance radio communication openings, allowing amateur radio operators to make contacts with stations that would normally be too far apart for reliable communication. During these openings, signals from distant stations (such as the UK to Germany) can be received with signal strengths of 10-20 dB over 9, making them sound like local stations. The propagation conditions change rapidly, with openings and closings occurring throughout the season, requiring operators to monitor and adapt to changing conditions.
