Solar Active Region (AR) 2403 is rotating toward the central meridian
and has produced six M class flares during the past 2 days. It
produced three M class flares during 22 Aug. The most intense event
was a short-lived M2.2 event peaking at 12:23 UT. There is a chance of
a small X class flare during the next 3 days. If the activity of AR
2403 continues to increase, an Earthward directed CME and major
geomagnetic storm are possible next week. H alpha solar telescopes
show a spectacular solar prominence on the North East limb of the
solar disk. A solar wind disturbance ahead of fast solar wind is
expected to impact Earth today, 23 Aug. This will cause active
geomagnetic conditions, possibly reaching minor storm levels.
Conditions for HF radio wave propagation are still unusually depressed
globally, but should gradually strengthen during the 4-week interval
approaching the September equinox.
