another significant M class flare during Jan 23-25. AR 2268 will
rotate into a geo-effective position next week. The fast solar wind
which arrived at Earth on Jan 21 is starting to decrease in speed. The
solar wind speed is presently fluctuating in the range 400 km/s to 450
km/s and it may decline further during Jan 23. Geomagnetic conditions
were active at the start of Jan 22, but then mostly quiet to
unsettled. Geomagnetic conditions are expected to be mostly quiet to
unsettled during Jan 23-24. Conditions for HF radio communication were
depressed across Southern Australia and strongly depressed across
Northern Australia during Jan 22. Conditions for HF radio have
recovered and are expected to be near predicted monthly values during
Jan 23-24.
