A 'severe solar wind shock' impacted Earth at 1632UTC yesterday.
This resulted in a big aurora, The A Index is 56. This is higher than
early February when VA3LK was getting good signals from DCF.
It will be interesting to see if this causes some good LF conditions.
If it does, it probably shows that the Solar Flare warnings are
useless as this aurora was preceded by 2 C-class and 1 M-class
flares which occur quite frequently.
For more info from the experts follow the three propagation links
from my web site.
