Highlights of Solar and Geomagnetic Activity 19 - 25 March 2018
Solar activity was very low. The sun was spotless and absent of
significant 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 19-25 March.
Geomagnetic field activity reached G1 (Minor) storm levels on 19
March and active levels on 23-25 March due to the influence of
recurrent, negative polarity CH HSS effects. Quiet to unsettled
conditions were observed on 20-22 March.
FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 26 MARCH - 21 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 at high levels on 26-28, 30-31 March and 01-02, 12-21
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 26 March and 12 April with active periods likely on 26,
29-30 March, and 11-15, 19, 21 April due to effects from multiple,
recurrent CH HSSs. Quiet to unsettled levels are expected for the
remainder of the outlook period.
