COMMENT: ASWFC SWF HF Communications Warning 84 was issued on
7 November and is current for 7-9 Nov. Maximum usable frequencies
(MUFs) on UT day 07-Nov were enhanced by up to 25% in Northern
Australia during local night and near predicted monthly values
in Southern Australia. A shortwave fadeout associated with the M
5.2 flare was observed from 07/0005UT to 07/0021UT. Spread F was
observed at Hobart during local night hours. Sporadic E was observed
at Brisbane. MUFs are expected to be near predicted monthly values
over 08-10 Nov. Mild degradations are possible over 09-10 Nov due to coronal
hole high speed wind stream effects. Shortwave fadeouts are possible.
