.24 hr Summary...
The geomagnetic field was at quiet with an isolated unsettled period.

.Forecast...
Quiet to unsettled levels are expected 21 Oct, with a chance for an
isolated active period, in response to CH HSS effects. Quiet to
unsettled conditions are expected 22 Oct as CH HSS effects begin to
wane. A mostly quiet geomagnetic field is expected 23 Oct.
