1B. SOLAR FORECAST
             09 Jul             10 Jul             11 Jul
Activity     Low to moderate    Low to moderate    Low to moderate
Fadeouts     Possible           Possible           Possible
10.7cm/SSN   130/84             130/84             135/89
COMMENT: A gradually increasing flux trend on ACE EPAM precursor 
data channel suggests a weak shock is enroute to the earth, possibly 
arriving middle of 9 July. However, futher LASCO imagery shows 
that the CME from yesterdays filament eruption did not expand 
greatly as it left the sun, staying in a realtively narrow north-west 
stream. This is expected to reduce geoeffectiveness of this event. 
Todays M1 was an impulsive event.
