An M5-flare was observed from solar region 1745 towards the west limb
of the sun around 1320UT (1120pm AEST). Energetic particles and an
impressive CME have been observed in association with this event. The
CME is expected to have a glancing impact at Earth during local night
of 24 May (AEST). Minor storm geomagnetic activity is possible from
this event. Low to moderate solar flare activity is expected to
continue. Light to moderate solar wind is expected for today
increasing to moderate to strong during 24-25 May. Geomagnetic
conditions at quiet to unsettled levels for today. Short-wave radio
fadeouts possible. High-frequency radio communications normal for
today at low-mid latitudes with significantly degraded conditions at
high latitudes due to energetic particle effects (PCA event).
