2. FORECAST (28 OCTOBER - 03 NOVEMBER)
Solar: 
Solar activity is expected to be at the R0 level this week.

Geomagnetic:  
G0-G1 geomagnetic conditions are expected on 29-Oct due to an 
equatorial coronal hole which is expected to reach a geoeffective
position on 29-Oct. G0 geomagnetic conditions, with a chance of 
G1 are expected over 30-Oct to 02-Nov while the high speed wind 
effects persist. G0 geomagnetic conditions are expected on 03-Nov  

Frequencies:  
Maximum usable frequencies (MUFs) are expected to be near predicted
monthly values. There is a chance of degradations over 29-Oct to 
02-Nov due to coronal hole high speed wind stream effects.
