Сонячно-активні області та спалахи

Solar flaring activity has been low over the past 24 hours, with few C-class flares. The strongest flare was a C1.2 flare (SIDC Flare 7140), peaking at 04:43 UTC on March 08, associated with SIDC Sunspot Group 762 (magnetic type beta). There are currently five numbered active regions on the solar disk. The most complex one is SIDC Sunspot Group 804 (NOAA Active Region 4381, magnetic type beta-gamma). SIDC Sunspot Group 812 (NOAA Active Region 4386) has rotated behind the west limb. SIDC Sunspot Group 762 has rotated on disk from the east limb, in the northeast 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.

Корональні викиди маси

A narrow Coronal Mass Ejection (SIDC CME 638) was observed in LASCO/C2 coronagraph imagery, lifting off from the northeast limb starting from 02:30 UTC on March 08. It is likely associated with a prominence eruption over the northeast limb 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.

Корональні діри

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

Сонячний вітер

Over the last 24 hours, the solar wind parameters (ACE and DSCOVR) were enhanced, likely due to the arrival of a high-speed stream from the northern, mid-latitude, negative polarity coronal hole (SIDC Coronal Hole 142), which crossed the central meridian on March 05. The solar wind speed initially increased from 350 km/s to 680 km/s and is currently around 580 km/s. The interplanetary magnetic field initially decreased from 12 nT to 5 nT and is currently around 8 nT. The Bz component varied between -6 nT and 6 nT. The interplanetary magnetic field angle phi was predominantly in the negative sector. Enhanced solar wind conditions are expected over the next 24 hours, under the continuous influence of the high-speed stream from SIDC Coronal Hole 142.

Геомагнетизм

Geomagnetic conditions globally were mostly active (NOAA Kp 4) during the last 24 hours, with an interval of minor storm levels between 00:00 UTC and 03:00 UTC on March 08. Geomagnetic conditions locally were mostly active (K Bel 4), reaching minor storm levels between 01:00 UTC 03:00 UTC on March 08. The geomagnetic storms are possibly linked to a high-speed stream arrival, from the northern, mid-latitude, negative polarity coronal hole (SIDC Coronal Hole 142). Mostly active conditions, with possible isolated minor storm intervals, are expected over the next 24 hours, due to the ongoing influence of the high-speed stream from SIDC Coronal Hole 142.

Рівні потоку протонів

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.

Потоки електронів на геостаціонарній орбіті

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 gradually increase 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, with an increase to moderate levels possible in the next 48 hours.
