well I decided to go look, here is what SWPC had to say about the CH winds...
.24 hr Summary...
ACE data indicated minor changes in the solar wind flow. Speed ranged
from 380 to 499 km/s. IMF total field intensity (Bt) ranged from 1 to 6
nT. IMF Bz was variable in the 4/-5 nT range. Phi data indicated an away
(+) solar sector orientation during most of the period until
approximately 22/0200 UTC when it changed to a toward (-) orientation.
.Forecast...
Solar wind speed is expected to gradually increase during 22 - 23 May a
a recurrent CH HSS becomes geoeffective. WSA-Enlil model runs predict
peak speeds around 500 km/s with this CH HSS. Wind speed is expected to
remain enhanced on 24 May.
.Forecast...
Geomagnetic field activity is
expected to increase to quiet to unsettled
levels on 22 May as a recurrent CH HSS becomes geoeffective. A further
increase to unsettled to
active levels is expected on 23 May as the CH
HSS intensifies. Activity is expected to decrease to quiet to unsettled
levels on 24 May as CH HSS effects subside.
