Slunečně aktivní oblasti a vzplanutí

Solar flaring activity during the last 24 hours has been low, with only C-class flares. The strongest flare was a C2.9 flare (SIDC Flare 7125), peaking at 00:30 UTC on March 03, associated with SIDC Sunspot Group 804 (NOAA Active Region 4381, magnetic type beta). There are currently six 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.

Vyhazování koronální hmoty

A Coronal Mass Ejection (SIDC CME 632) was observed in LASCO/C2 coronagraph imagery, lifting off the west limb around 18:50 UTC on March 02. It is most likely associated with a prominence eruption over the west limb, observed in SUVI 304 data starting from 17:50 UTC. It is not expected to impact Earth. A wide CME (SIDC CME 633) was observed in LASCO/C2 and STEREO-A coronagraph imagery, lifting off the east limb around 11:00 UTC on March 03. It is likely a backsided event and it is not expected to impact Earth. No other Earth-directed CMEs were observed in the available coronagraph imagery during the last 24 hours.

Solární bouře

Over the last 24 hours, the solar wind parameters (ACE and DSCOVR) reflected mostly slow solar wind conditions. The solar wind speed increased from 330 km/s to 400 km/s. The interplanetary magnetic field increased from 4 nT to 9 nT. The Bz component varied between -10 nT and 6 nT. The interplanetary magnetic field angle phi was predominantly in the positive sector. Mostly slow solar wind conditions are expected over the next 24 hours.

Geomagnetismus

Geomagnetic conditions globally were quiet to unsettled (NOAA Kp 1 to 3- ) during the last 24 hours. Geomagnetic conditions locally were quiet (K Bel 1 to 2) during the last 24 hours. Mostly quiet conditions are expected over the next 24 hours.

Úrovně protonového toku

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.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux measured by GOES 18 and GOES 19 decreased below the 1000 pfu threshold after 04:30 UTC on March 03. The 24-hour electron fluence was at moderate levels and is expected to remain so over the next 24 hours.
