FM Loggings July 17 - Aurora

An aurora opening with refracted, distorted signals occurred around 19:30Z, only audible on the antenna pointing NW. As usual, only stations from mid- and northern Sweden and Finland were heard, typically 400 to 600 km away. Those positively identified (no RDS) are shown below.


K indices at the time were around 5, and the auroral oval was quite strong over the area, as shown below. Later on, the proton flux went through the roof.



 A bit later a couple of stations from Iceland showed up through normal Es propagation.
