COMMENT: IPS HF Communications Warning 25 was issued on 27 May
and is current for 28-30 May. Variable depressions to 35% observed
in the Australian region as EUV levels decline due to a decrease
in sunspot numbers. Expect similar conditions over the next three
days. Note MUFs are expected to remain lower than predicted due
to this decrease in EUV.
