Looks like HF communications will be affected over the next few days.  Additional information can be found on the HF Radio dashboard ( http://www.swpc.noaa.gov/communities/radio-communications )  from NOAA's Space Weather Prediction Center ( http://www.swpc.noaa.gov ) .

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 4 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jun 22-Jun 24 2015 is 7 (NOAA Scale
G3).

21-00UT        6 (G2)     3          3

Rationale: G2 (Moderate)-G3 (Strong) geomagnetic storms are likely on
days one-two (22-23 Jun) due to the arrival of a full-halo CME from 21
Jun. 24 Jun should see a return to active conditions as CME effects
wane.
