Slunečně aktivní oblasti a vzplanutí

Solar flaring activity during the last 24 hours has been low, with few C-class flares. The strongest flare was a C1.9 flare (SIDC Flare 7136), peaking at 22:42 UTC on March 05, associated with SIDC Sunspot Group 804 (NOAA Active Region 4381, magnetic type beta). There are currently five numbered active regions on the solar disk. The most complex one is SIDC Sunspot Group 801 (NOAA Active Region 4378, magnetic type beta-delta). The solar flaring activity is expected to be low to moderate over the next 24 hours, with C-class flares very likely and M-class flares probable.

Vyhazování koronální hmoty

A Coronal Mass Ejection (SIDC CME 635) was observed in LASCO/C2 coronagraph imagery, lifting off from the west limb around 19:30 UTC on March 05. It is likely associated with a prominence eruption over the west limb and it is not expected to impact Earth. SIDC CME 636 was observed in LASCO/C2 and STEREO-A coronagraph imagery, lifting off from the southeast limb around 04:15 UTC on March 06. It is likely associated with a filament eruption in the southeast quadrant, near Sunspot Group 811 (NOAA Active Region 4385), observed in SUVI 304 data starting from 02:50 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.

Koronální díra

The northern, mid-latitude, negative polarity coronal hole (returning SIDC Coronal Hole 142) has been crossing the central meridian since March 05.

Solární bouře

Over the last 24 hours, the solar wind parameters (ACE and DSCOVR) reflected slow solar wind conditions. The solar wind speed remained below 390 km/s, reaching a minimum of 340 km/s. The interplanetary magnetic field was mostly around 5 nT. The Bz component varied between -3 nT and 5 nT. The interplanetary magnetic field angle phi was initially mostly in the positive sector, flipping to negative at 09:00 UTC on March 06. Enhanced solar wind conditions are expected over the next 24 hours, due to the probable arrival of a high-speed stream from the equatorial, negative polarity coronal hole (SIDC Coronal Hole 149).

Geomagnetismus

Geomagnetic conditions globally reached unsettled levels (NOAA Kp 3- ) between 03:00 UTC and 06:00 UTC on March 06. Geomagnetic conditions locally were at quiet levels (K Bel 1 to 2) during the last 24 hours. Active to minor storm conditions (NOAA Kp 4 to 5) are expected over the next 24 hours, due to the likely arrival of a high-speed stream from the equatorial, negative polarity coronal hole (SIDC Coronal Hole 149).

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 was below the 1000 pfu threshold during the last 24 hours and it is expected to remain so over the next 24 hours. The 24-hour electron fluence was at normal levels and it is expected remain so over the next 24 hours.
