2. FORECAST (22 OCTOBER - 28 OCTOBER)
Solar: Very Low to Low solar activity is expected for the
forecast week as the current regions on disc remain quiet and 
relatively unchanged in size. No significant active returning 
regions expected.

Geomagnetic: Mostly Quiet to Unsettled conditions expected
with possible Active periods for high latitudes on 23Oct-25Oct
due to a thin coronal hole extending from the north pole to
the equator of the sun being in geoeffective position.

Frequencies: Depressed MUFs of ~20% for mid to high latitudes 
during local day and during local night for low latitudes 
for 22Oct-26Oct, with otherwise near predicted monthly values.
No SWF expected.
