2. FORECAST (01 JUNE - 07 JUNE) 
MUFS: Variable ionospheric support expected for the 01Jun-04Jun with 
occasional MUF depressions or near predicted monthly values. 
Possible MUF depressions of 10%-30% for 05Jun-07Jun from anticipated
increase in geomagnetic activity from a recurrent coronal hole. 

Propagation conditions: Fair on 5-6 Jun - otherwise normal. 
No SWFs expected due to Low solar activity.

T index: 46

3. OUTLOOK (08 JUNE - 08 JULY)
Degraded HF propagation conditions possible:
2-3 Jul,  7 Jul

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.
