2. FORECAST (21 OCTOBER - 27 OCTOBER)
Solar: 
Solar activity is expected to be at the R0 level this week.

Geomagnetic:  
G0-G1 geomagnetic conditions are expected on 23-24 Oct due to a
southern hemisphere coronal hole currently crossing the central
meridian. G0 geomagnetic conditions are expected on other days.

Frequencies:  
Maximum useable frequencies (MUFs) are expected to be near 
predicted monthly values. There is a chance of degradations on
23-24 Oct due to increased geomagnetic activity.
