Loud and Clear via Aurora

Mike, KA3JAW, wrote that the reason for the loud and clear transatlantic signals heard here on Wednesday evening was because during that time, aurora was active between my Connecticut location and Polskie Radio Jedynka in Solec Kujaski, Poland.

The center of the aurora was near 60°N 37.5°W (see figure above). The orange line indicates the path between my location and Poland. The thin yellow line is the mid-point at 2,024 miles.

A minor G-1 class geomagnetic storm was the result of a coronal hole spewing both low and high speed streams of solar winds towards Earth, which sparked the aurora.
