COMMENT: IPS HF Communications Warning 33 was issued on 12 August
and is current for 13-15 Aug. MUFs have ranged between predicted
monthly values and moderate depressions. Expect this trend to
prevail over the next three days due to low EUV resulting from
low sunspot numbers for this period in the solar cycle. Furthermore,
HF conditions may degrade on the 16 August due to an increase
geomagnetic activity.
