2. FORECAST (02 AUGUST - 08 AUGUST)
Solar: 
Frequent solar flares are expected this week. Frequency may decrease after
02-Aug, but is still expected to remain high.
Solar flares of R1-R3 level are expected this week.

Geomagnetic:  
G0-G1 geomagnetic conditions are expected on 04-Aug due to multiple soft CME
arrivals on this day. G0 is expected 
on all other days.

Frequencies:  
MUFs near predicted monthly values. Mild depressions of 10-15% may be seen early
in the week.
