2. FORECAST (02 APRIL - 08 APRIL)
Solar: Low

Geomagnetic:  Mostly quiet on 02 and 03 April. Mostly unsettled
to active on 04 April and first half of 05 April with some
possibility of isolated minor storm conditions, especially at 
high latitudes. Mostly quiet thereafter. 

Frequencies:  Depressions of 5 to 15 % possible on 04 April and 
first half of 05 April, especially at high latitudes. Otherwise 
MUFs near normal. SWFs possible during the first four days of 
the period. 

PLEASE 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.
