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 7133), peaking at 07:12 UTC on March 05, associated with SIDC Sunspot Group 812 (magnetic type beta). There are currently five numbered active regions on the solar disk. The most complex ones have a beta magnetic type. SIDC Sunspot Groups 806, 809 and 810 have decayed into plage. SIDC Sunspot Group 812 has emerged in the northwest quadrant. 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 faint Coronal Mass Ejection (SIDC CME 634) was observed in LASCO/C2 and STEREO-A coronagraph imagery, lifting off the west limb around 03:30 UTC on March 05. It is 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.

Koronální díra

An equatorial, negative polarity coronal hole (SIDC Coronal Hole 149) has been crossing the central meridian since March 04. A northern, mid-latitude, negative polarity coronal hole (returning SIDC Coronal Hole 142) is crossing the central meridian. An associated high- speed stream may arrive at Earth starting from March 08.

Solární bouře

Over the last 24 hours, the solar wind parameters (ACE and DSCOVR) reflected a return to slow solar wind conditions. The solar wind speed decreased from 450 km/s to 380 km/s. The interplanetary magnetic field was between 4 nT and 6 nT. The Bz component varied between -4 nT and 4 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 at quiet levels (NOAA Kp 1 to 2). Geomagnetic conditions locally reached unsettled levels (K Bel 3) between 00:00 UTC and 02:00 UTC on March 05. 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 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.
