2. FORECAST (27 JANUARY - 02 FEBRUARY)
Solar: 
Very Low to Low solar conditions expected for the next 7 days with 
no returning active regions. 

Geomagnetic:  
Quiet to Unsettled conditions with possible isolated Active periods
for day 1 and 2 of this forecast, due to the brief increase in
geomagnectic activity from the current coronal hole.

Frequencies  
MUFs near predicted monthly values for most of this forecast period.
Depressed 10%-20% during local night and dawn over Southern Aus/NZ
regions for the first two days. No SWFs expected. 


PLEASE NOTE: 
At this time of the solar cycle, space weather conditions
are frequently determined by short timescale events, not
able to be forecasted a week in advance.
