The Earth has been inside of a high-speed solar wind stream coming
from a coronal hole for the last few days. While there were some
active geomagnetic conditions at the onset of the event, and thhe
solar wind speed peaked at over 600 km/sec, the activity level has
diminished, as has the solar wind speed. There is a very small
remnant of sunspot region 798/808 visible now. As regular readers
will remember, this sunspot region fired off some massive flares
during its two previous passes, one being an X-17 event. No chance of
that happening now though, as what remains is barely visible. Loook
for conditions to remain quiet for the next several days.
