Highlights of Solar and Geomagnetic Activity 03 - 09 March 2025

Solar activity was moderate on 05 and 07 March with two M1 flares,  neither had any significant radio or CMEs associated. The rest of the period was at low levels. No significant CMEs were observed. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 04 March. Low to moderate levels were observed for the rest of the period. 

Geomagnetic field activity reached moderate levels on 09 March due to negative polarity CH HSS influences. Solar wind speeds reached peaks of near 675 km/s. Minor storm levels were observed on 08 March in response to the same CH HSS effects. Active levels were observed late on 04 March into early on 05 March due to suspected weak CME influences. Quiet to unsettled conditions prevailed for the remainder of the period. 

Forecast of Solar and Geomagnetic Activity 10 March - 05 April 2025

Solar activity is expected to be at low to moderate levels for the outlook period. No noteworthy regions are expected to return. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate to high levels on 29-31 March due to recurrent CH HSS influences. Normal to moderate levels are expected for the rest of the outlook period. 

Geomagnetic field activity is expected to be at minor storm levels for 10-11 March, 18 March, 26-27 March, and 05 April, all due to recurrent CH HSS influences. Quiet to unsettled levels are expected for the remainder of the period. (subject to change with any CME activity).
