2. FORECAST (09 APRIL - 15 APRIL)
Solar: 
Very Low to Low

Geomagnetic:  
Generally Quiet to Unsettled conditions with possiblility of Active 
to Minor Storm conditions on 12-13 April due to possible arrival of 
halo CME, which occurred on 8 April.

Frequencies:  
MUFs near predicted monthly values expected with possibility of mild
depressions at mid to high latiudes on 13-14 April due to possibility 
of geomagnetic storm on 12-13 April.
