Solaraktive Regionen und Flares

Solar flaring activity during the last 24 hours has been low, with only C-class flares. The strongest flare was a C4.5 flare (SIDC Flare 7119), peaking at 04:38 UTC on March 02, associated with SIDC Sunspot Group 805 (NOAA Active Region 4384, magnetic type beta). There are currently seven numbered active regions on the solar disk. The most complex ones have a beta magnetic type. The 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.

Koronaler Massenauswurf

A slow Coronal Mass Ejection (SIDC CME 630) was observed in LASCO/C2 and STEREO-A coronagraph imagery, lifting off around 10:30 UTC on March 02. It is associated with a prominence eruption near the northeast limb, observed in SUVI 304 data starting from 09:30 UTC. It is not expected to impact Earth. A second CME (SIDC CME 631) was observed in LASCO/C2 coronagraph imagery, lifting off around 10:40 UTC on March 02 from the west limb. It is associated with a filament eruption in the nortwest quadrant, observed in AIA 304 data starting from 10:00 UTC. It is not expected to impact Earth. No other Earth-directed CMEs were observed in the available coronagraph imagery during the last 24 hours.

Sonnenwind

Over the last 24 hours, the solar wind parameters (ACE and DSCOVR) reflected slow solar wind conditions. The solar wind speed decreased from around 400 km/s to 340 km/s. The interplanetary magnetic field values varied between 4 nT and 6 nT. The Bz component was between -4 nT and 4 nT. The interplanetary magnetic field angle phi was predominantly negative between 13:45 UTC and 23:50 UTC on March 01, then flipping to mostly positive values. Slow solar wind conditions are expected over the next 24 hours.

Geomagnetismus

Geomagnetic conditions globally and locally were quiet (NOAA Kp 1-2, K Bel 1-2) during the last 24 hours. Mostly quiet conditions are expected over the next 24 hours.

Protonenflusswerte

The greater than 10 MeV proton flux was below the 10 pfu threshold during the last 24 hours. It is expected to remain below the threshold level over the next 24 hours.

Elektronenflüsse im geostationären Orbit

The greater than 2 MeV electron flux measured by GOES 18 was above the 1000 pfu threshold until 06:00 UTC on March 02. The greater than 2 MeV electron flux measured by GOES 19 remained above the 1000 pfu threshold during the last 24 hours. The 24-hour electron fluence was at moderate levels and is expected to remain so over the next 24 hours.
