2. FORECAST (14 JANUARY - 20 JANUARY)
Solar: Very Low solar activity expected for the first half 
of the forecast week. Possible C-class events from region(s)
due to rotate onto the visible disc in the latter half
of this forecast period.

Geomagnetic: Unsettled conditions with isolated Active periods
at mid to high latitudes expected for 14Jan-16Jan and possible
for 19Jan-20Jan due to coronal hole effects. Otherwise mostly 
Quiet conditions. 

Frequencies: Periods of depressed MUFs ranging from 10%-30% 
expected for low to mid latitudes for the forecast period.
Disturbed HF conditions possible for high latitudes.
