[Ips-hf-warning] IPS HF COMMS WARNING issued 2331 UT on 08 Nov 2015

[rwc]

SUBJ: IPS HF RADIO COMMUNICATIONS WARNING 15/69
ISSUED AT 2331UT/08 NOVEMBER 2015
BY THE AUSTRALIAN SPACE FORECAST CENTRE.

Observed MUF's for the Australasia regions on the UT day 08 Nov 
were strongly degraded. This degradation is due to negative storm 
effects in ionosphere following the passage of the CME. The two 
day outlook is for HF conditions to remain degraded. The onset 
of high speed solar streams from the approaching very large recurrent 
positive northern coronal will further delay the recovery of 
MUFs.

DEGRADED HF PROPAGATION CONDITIONS EXPECTED
FROM 09-11 NOVEMBER 2015
IF COMMS DIFFICULTIES EXPERIENCED TRY A LOWER FREQUENCY BAND
