Highlights of Solar and Geomagnetic Activity
12 - 18 March 2018

Solar activity was very low throughout the period. The only numbered
regions were 2701 (S12, L=99, class/area=Axx/10 on 15 March) and
2702 (N22, L=109, class/area=Bxo/5 on 17 March). Neither region
managed any flare activity. No Earth-directed CMEs were observed
during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels on 16-18 March. Normal levels were observed on 12-15

Geomagnetic field activity reached G2-Moderate storm levels on 18
March and active levels on 14-17 March due to the influence of a
negative polarity CH HSS. Quiet to unsettled levels were observed
throughout the rest of the week. is the U.S. government's official web portal to all federal, state and local government web resources and services.
