Attività solare

Sommario di 24 ore

Solar activity reached moderate levels. Region 4396 (N20E55, Bxo/beta) was numbered this period, but was otherwise unremarkable. Region 4392 (S16E28, Cso/beta) produced the strongest flare of the period, an M1.0/Sf flare at 15/0939 UTC. Coronal dimming was observed with this event in GOES Suvi 195 imagery and an associated narrow and faint CME was then observed in LASCO C2 imagery at approximately 15/1036 UTC. Modeling of this event determined a miss behind and south of Earth. No Earth-directed CMEs were observed.

Previsione

Solar activity is expected to be at low levels, with a slight chance for M-class (R1-R2/Minor-Moderate) flares through 18 Mar.

Particelle energetiche

Sommario di 24 ore

The greater than 2 MeV electron flux reached high levels with a peak flux of 1,430 pfu at 15/1900 UTC. The greater than 10 MeV proton flux was at background levels.

Previsione

The greater than 2 MeV electron flux is expected to continue to reach high levels through 18 Mar. The greater than 10 MeV proton flux is expected to continue at background levels through 18 Mar.

Vento Solare

Sommario di 24 ore

Solar wind parameters reflected the continued influence of a positive polarity CH HSS. Total field was at 5-6 nT and the Bz component was +/- 5 nT. Solar wind speeds gradually decreased from peaks near 700 km/s to end the period near 600 km/s. Phi was predominantly in a positive solar sector.

Previsione

Solar wind parameters are expected to remain elevated, but gradually decline over the next three days (16-18 Mar).

Geospaziale

Geomagnetic field activity ranged from quiet to active levels.

Previsione

Geomagnetic field activity is expected to be primarily quiet to unsettled through 18 Mar with isolated active periods persisting on day one (16 Mar).
