[ips-sf] ASWFC Summary Forecast for 24 March - issued 2054UT/23-Mar-2023 [SEC=OFFICIAL]

[rwc]

Geomagnetic activity in the Australian region has unexpectedly reached
ASWAS G2 level overnight. The planetary Kp reached G3 for one K
period. The activity was associated with a with a gradual increase in
the solar wind total magnetic field strength together with an
increasing southward drift of the interplanetary magnetic field (IMF)
Bz component. The IMF Bz component has been more steadily southward
since 23/1700UT and a further G1-2 period is likely. The southern
Australian region ionosphere is likely to be depressed after dawn this
morning, with degraded HF communication conditions.
