Predicted Monthly T index for April:  86

2. FORECAST (30 APRIL - 06 MAY) 
MUFS: MUFs near or above predicted monthly values.
MUFs probably reduced 30th May due to Unsettled geomagnetic activity.
No significant recurrent activity expected from 27 day solar rotation of
active regions.

Propagation conditions: Normal in the absence of major geomagnetic disturbances.

T index: 86

3. OUTLOOK (07 MAY - 06 JUNE)
Degraded HF propagation conditions possible but
significant degraded periods are not expected.

PLEASE NOTE:
Space weather conditions can frequently be determined by short 
timescale events that cannot be forecast a week in advance,
particularly at solar maximum.
