Сонячно-активні області та спалахи

Solar flaring activity was low over the past 24 hours, with only C-class flares. The strongest flare was a C6.1 flare (SIDC Flare 7097), peaking at 02:06 UTC on March 01, which was associated with SIDC Sunspot Group 803 (NOAA Active Region 4380, magnetic type beta). There are currently seven numbered active regions on the solar disk. SIDC Sunspot Group 805 (magnetic type beta) has rotated on disc from the east limb, in the northeast quadrant. SIDC Sunspot Groups 806, 807 (both magnetic type beta) and SIDC Sunspot Group 808 (magnetic type alpha) have emerged in the northwest quadrant. SIDC Sunspot Groups 802 (NOAA Active Region 4379) has decayed into a plage region. 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.

Корональні викиди маси

No Earth-directed Coronal Mass Ejections (CMEs) were observed in the available coronagraph imagery in the last 24 hours.

Сонячний вітер

Over the past 24 hours, the solar wind parameters (ACE and DSCOVR) reflected mostly slow solar wind conditions. Speed values ranged between 370 km/s and 450 km/s. The interplanetary magnetic field values were between 3 nT and 5 nT. The Bz component varied between -4 nT and 4 nT. The interplanetary magnetic field angle was mostly in the negative sector. Mostly slow solar wind conditions are expected over the next 24 hours.

Геомагнетизм

Geomagnetic conditions globally and locally were mostly at quiet to unsettled levels (NOAA Kp 2 to 3-, K BEL 1 to 3). Mostly quiet conditions, with possible unsettled intervals, are expected over the next 24 hours.

Рівні потоку протонів

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

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux measured by GOES 19 was mostly above the 1000 pfu threshold in the last 24 hours and fell below the 1000 pfu threshold between 01:30 UTC and 04:30 UTC on March 01. The greater than 2 MeV electron flux measured by GOES 18 was above the 1000 pfu threshold until around 05:00 UTC on March 01 and has remained below the threshold since. The greater than 2 MeV electron flux is expected to remain around the 1000 pfu threshold levels in the next 24 hours. The 24-hour electron fluence is presently at moderate levels and is expected to remain so over the next 24 hours.
