SUMMARY FOR 29 OCTOBER AND FORECAST FOR 30 OCTOBER - 01 NOVEMBER
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 29 Oct:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 29 Oct:  74/11


1B. SOLAR FORECAST
             30 Oct             31 Oct             01 Nov
Activity     Very low           Very low           Very low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    75/13              75/13              75/13
COMMENT: Solar activity remained very low today as well. No flare 
activity was recorded. The solar wind speed gradually decreased 
from 400km/s to 360 km/s by the time of this report. The north-south 
component of the interplanetary magnetic field (Bz) remained 
close to the normal value throughout the UT day today. Solar 
activity is expected to remain at very low levels for the next 
few days.
