2. FORECAST (03 APRIL - 09 APRIL)
Solar: Very Low. There is currently one numbered region 
on the visible disc, region 2759 located at N28E30 which 
has remained quiet and stable over the last few days. 

Geomagnetic:  Quiet to Unsettled conditions. Chance of Active
periods for Mid-High latitudes 05Apr-6Apr due to coronal hole
effects.

Frequencies:  MUFs near predicted monthly values. No SWF's 
expected.
