2. FORECAST (02 SEPTEMBER - 08 SEPTEMBER)
Solar: 
R0 conditions, with a chance of R1 are expected for 02-03 Sep.
R0-R1 conditions are expected for the rest of the week as a new 
active region rotates onto the northeast quadrant of the solar disk.

Geomagnetic:  
G0 geomagnetic conditions are expected on 02-Sep.
G0 geomagnetic conditions, with a chance of G1 are expected 
on 03-05 Sep due to coronal hole high speed wind stream effects.
G0 geomagnetic conditions are expected on other days.

Frequencies:  
Chance of isolated minor shortwave fadeouts over the week.
HF depressions possible over 03-05 Sep due to coronal hole high
speed wind stream effects, particularly during local night.
MUFs near predicted monthly values to 15% depressed during local 
night on other days.
