Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C2.5 flare peaking on March 09 at 18:53 UTC, from a currently unnamed region from behind the east limb. A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 423 (NOAA Active Region 4012) is currently the most complex active region (Beta-Gamma magnetic configuration). Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Koronalny wyrzut masy

No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

Dziury koronalne

A negative polarity coronal hole is crossing the central meridian. A high-speed stream from this coronal hole may impact the solar wind environment near Earth on the end of March 12.

Wiatr słoneczny

Earth continues to be under the influence of high speed stream (HSS) from the large, negative polarity coronal hole which crossed the central meridian on March 05. The solar wind speed slightly decreased from 630 km/s to 530 km/s. The interplanetary magnetic field decreased from 6 to 4 nT. The North-South component (Bz) fluctuated between -5 nT and 5 nT. In the next 24 hours, solar wind conditions at Earth may be enhanced due to the potential arrival of the ICME.

Geomagnetyzm

Geomagnetic conditions were globally and locally active on March 09 between 12:00 and 15:00 UTC, and were quiet to unsettled (Kp 3 and K Bel 3) for the rest of the time. Active conditions are expected in the next 24 hours due to the potential ICME arrival.

Poziomy przepływu protonów

The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as measured by the GOES-18 satellite shortly crossed the 1000 pfu alert threshold on March 09 12:30 UTC. The greater than 2 MeV electron flux as measured by the GOES-16 satellite remained below the 1000 pfu alert threshold. The greater than 2 MeV electron flux is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
