2. FORECAST (10 NOVEMBER - 16 NOVEMBER)
Solar: Low to moderate

Geomagnetic:  10 Nov: Mostly unsettled.
              11-13 Nov: Disturbed conditions are expected due
	      to the influence of a large coronal hole,
	      the effect possibly being compounded with the
	      arrival of shock associated with CME observed
              together with an M7 proton flare on the 8 NOV.
	      Storm periods possible for this period.
	      14-16 Nov: Returning to mostly unsettled.

Frequencies:  10 Nov: Mostly normal for low-mid lats with high
	      levels of absorbtion for high lats.
              11-13 Nov: High lats still suffering high absorbtion
	      and very poor HF conditions, with low-mid lats
	      becoming mildly degraded.
	      14-16 Nov: Conditions returning to normal for all
	      latitudes.

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.
