2. FORECAST (02 DECEMBER - 08 DECEMBER)
Solar: An increase flare activity (ASWAS R1) is 
possible this week.


Geomagnetic:  
Isolated G1 periods during 02-03 Dec and on 07-08 Dec. 
G0 conditions on other days.

Frequencies:  
Briefly depressed after local dawn during 02-03 Dec and
on 08-Dec. MUFs near predicted monthly values on other days.
Isolated shortwave fadeouts on daylight HF circuits 
are possible, impacting lower HF frequencies.
