CME

It looks like the coming days (especially today) could see quite disturbed solar conditions due to a coronal mass ejection (CME) on the sun. I am not clever enough to know how this will effect HF and low VHF.

Coronal mass ejection (CME)

 At the moment, we have a CME hitting the Earth. This looks minor.

CME triggered auroras?

Southgate News reports that there is a risk of a coronal mass ejection causing auroras this week. In the past I have worked stations via auroras with QRP on 6m CW and 10m SSB. A geomagnetic storm is likely even if the CME debris misses Earth.

Aurora?

The BBC was forecasting aurora sightings possible in the north of Scotland tonight and Southgate News talks about a CME event hitting the earth.
