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 08 February follow. Solar flux 94 and mid-latitude A-index 4. The mid-latitude K-index at 1200 UTC on 09 February was 1 (7 nT). Space weather for the past 24 hours has been minor. Radio blackouts reaching the R1 level occurred. Space weather for the next 24 hours is expected to be minor. Radio blackouts reaching the R1 level are expected.

What does this mean for DXers?
