Solar activity during the past 24 hours was low with four C-flares.
The outlook for the next 24 hrs is for low to moderate solar activity
with C class flares likely and isolated chance of stronger M class
flares. The solar winds are currently very strong, nearly 800 km/s.
This is caused by high speed streams emanating from a recurrent, large
equatorial coronal hole now at geoeffective position on the solar
disk. Should the IMF Bz turn strongly southward for few hours,
currently Bz is near 0 nT, severe geomagnetic storms could occur
during such high solar wind conditions. There is good chance of aurora
sightings this evenings from Southern Australian regions, possibly
extending at times to Central regions. Conditions for HF radio wave
propagation are expected to be degraded mainly in the high and mid
latitudes over the next few days.
