Highlights of Solar and Geomagnetic Activity
01 - 07 February 2021

Solar activity was at very low levels under a mostly spotless disk.
No Earth-directed CMEs were observed in available coronagraph
imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was was
at normal to moderate levels on 02-05 and 07 Feb. High levels
occurred on 01 and 06 Feb with a maximun flux of 1,920 pfu observed
at 01/1655 UTC.

Geomagnetic field activity ranged from quiet to G1 (Minor) storm
levels. Quiet activity was observed on 01 Feb, but increased to
quiet to active levels on 02-05 Feb due to negative polarity CH HSS
influence. Quiet to G1 (Minor) storm levels were observed on 06-07
Feb due to positive polarity CH HSS influence. A maximum wind speed
of 610 km/s was observed on 03/0540 UTC associated with the negative
polarity CH HSS.
