2. FORECAST (29 NOVEMBER - 05 DECEMBER)
Solar: Low to moderate

Geomagnetic:  Mostly quiet to unsettled early in the week, 
unsettled to active from 30 November to 03 December with 
possibility of going upto minor storm level, declining to 
unsettled to quiet levels towards the end of the period. 

Frequencies:  Periods of depressions from 5 to 20 % expected 
from 30 November to 03 December, otherwise MUFs near normal. 
SWFs possible.

PEASE 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.
