Highlights of Solar and Geomagnetic Activity 06 - 12 March 2017
Solar activity was at very low levels throughout the reporting period. No CMEs observed in available SOHO LASCO imagery were determined to be Earth-directed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 06-08 Mar. Normal to high levels were observed on 09 Mar and moderate to high levels were observed on 10 Mar. On 11 Mar, a return to normal to high levels were observed, with moderate to high levels ending the period on 12 Mar. Sustained levels of electron flux was caused by continuous influence of a CH HSS throughout the reporting period.
Geomagnetic field activity ranged from quiet to G1 (Minor) levels during the reporting period due to a negative polarity, CH HSS that persisted throughout most of the week. On 06 Mar, quiet to G1 (Minor) levels represented a peak in geomagnetic activity caused by 650 km/s solar wind speeds, the highest levels observed from the CH HSS. A very gradual decline in solar wind speeds caused unsettled to active conditions on 07 Mar followed by quiet to active levels on
08-10 Mar. Quiet to unsettled conditions were observed on 11 Mar. An isolated period of active conditions, associated with a sustained period of southward Bz, was observed early on 12 Mar which quickly transitioned to quiet conditions for the rest of the day.
Forecast of Solar and Geomagnetic Activity 13 March - 08 April 2017
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 13-17 Mar, 19-20 Mar, 24 Mar, and 29 Mar - 08 Apr due to influences from multiple, recurrent, CH HSSs. Normal to moderate levels are expected on 18 Mar, 21-23 Mar, and 25 Mar-28 Mar.
Geomagnetic field activity is expected to be at quiet to G2 (Moderate) levels over the next 27 days. Unsettled conditions are likely on 13-17 Mar, 19 Mar, 22 Mar, 24 Mar, 01 Apr, 03-05 Apr and 08 Apr. Active conditions are likely on 18 Mar, 23 Mar, 01 Apr, and 03-05 Apr. G1 (Minor) conditions are likely on 30-31 Mar and 02 Apr. G2 (Moderate) conditions are likely on 28-29 Mar. All enhancements in geomagnetic activity are due to the influences of multiple,
anticipated, recurrent CH HSSs. Mostly quiet conditions are likely for the remaining days of the outlook period.
