[Ips-hf-warning] ASWFC HF SWF COMMS WARNING issued 0425 UT on 30 Sep 2022 [SEC=OFFICIAL]

SUBJ: ASWFC HF RADIO COMMUNICATIONS WARNING 22/76
ISSUED AT 0422UT/30 SEPTEMBER 2022
BY THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE.

A previously flare active solar region is returning to the northeast 
solar limb and is rotating onto the solar disk. An M1 flare was 
just observed at 0402UT on 30-Sep. As the region has not rotated 
onto the disk flare probabilities cannot be estimated from magnetic 
complexity. However, current activity on the limb suggests that 
further flare events are possible. The returning region produced 
two R2 level events as it rotated off disk on its previous 
transit.

DEGRADED HF PROPAGATION CONDITIONS EXPECTED
FROM 30 SEPTEMBER 2022 TO 02 OCTOBER 2022
IF COMMS DIFFICULTIES EXPERIENCED TRY A HIGHER FREQUENCY BAND
