2. FORECAST (07 NOVEMBER - 13 NOVEMBER)
Solar: 
R2-R3 level activity is expected in the first half of the week.
A decrease in activity is possible in the second half of the week.

Geomagnetic:  
G3-G4 geomagnetic activity is expected on 07-Nov. G1 conditions, with
a chance of G2 and G0 conditions, with a chance of G1 are expected on
08-09 Nov respectively due to coronal hole high speed wind stream effects
combined with two anticipated coronal mass ejection impacts. G0 conditions
are expected for 10-13 Nov.

Frequencies:  
Depressions of up to 15% are expected on 07 and 09-Nov whilst depressions of
up to 30% are expected on 08-Nov due to anticipated geomagnetic activity.
Conditions are expected to recover towards monthly predicted values over 
10-13 Nov.
