We are currently experiencing the most severe solar storm in very many years with HF very badly disturbed. There are auroras expected far further south than normal. This is a result of a CME event on the Sun interacting with the magnetic field of our planet.
If the weather is clear, check for a visual aurora!
It is also worth keeping eyes and ears alert for auroral propagation on 10m, 6m, 4m and 2m. I have in the past worked stations via aurora using QRP SSB and CW with very simple wire antennas on 10m and 6m. As frequency goes down SSB becomes more possible. What may be a very rough hissy CW note on 2m maybe a fairly decent SSB signal on 10m. The 10m and 6m bands are very worth a try when there is an aurora about.
