Solar-terrestrial indices

Indices from the U.S. NOAA Space Weather Prediction Center in Boulder Colorado, updated every three hours and published here in real time:

Solar-terrestrial indices for 30 November follow. Solar flux 167 and estimated planetary A-index 5. The estimated planetary K-index at 0300 UTC on 01 December was 4.33. No space weather storms were observed for the past 24 hours. Space weather for the next 24 hours is predicted to be strong. Geomagnetic storms reaching the G3 level are likely.

What does this mean for AM DXers?
