2. FORECAST (12 APRIL - 18 APRIL)
Solar: Moderate to low. M class flare activity expected first half
       of week.

Geomagnetic:  active conditions expected 12-14 Apr, with chance
              of isolated minor storm periods 13 Apr, due to
              recent mass ejections.

Frequencies:  degraded conditions late 12-13 Apr, chance of
              mild depression 13 Apr. Mostly near to 20% above 
              predicted monthly values.
              SWFs probable.

PEASE NOTE: 
At this time of the solar cycle, space weather conditions
are frequently determined by short timescale events, not
able to be forecasted a week in advance.
