COMMENT: IPS HF Communications Warning 68 was issued on 6 November
and is current for 6-8 Nov. Observed MUF's for the Australasia
regions on the UT day 06 Nov were about 25% below the predicted
monthly values. Strong geomagnetic activity on 03-05 Nov associated
with the equatorial coronal hole has caused this MUF degradation.
MUFs are expected to remain poor for the next 3 days due the
combined effect of 1) the arrival of the CME at Earth associated
with M3.7 flare from Nov 04/1352 UT and 2) the expected arrival
of high speed solar streams from a very large recurrent positive
northern coronal hole late on UT day Nov 8.
