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
March.
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.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 19 MARCH - 14 APRIL 2018
Solar activity is expected to be at very low levels throughout the
outlook period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be high levels on 19-20, 22-26 March, and 12-14 April.
Normal to moderate levels are expected for the rest of the period.
Geomagnetic field activity is likely to be at G1 (Minor) storm
levels on 19 March and 12 April with active periods likely on 20-24
March and 11, 13-14 April, due to effects of multiple recurrent CH
HSSs. Quiet to unsettled levels are expected for the remainder of
the outlook period.
