Сонячно-активні області та спалахи

Solar flaring activity has been low over the past 24 hours, with only a C1.0 flare (SIDC Flare 7138) identified, peaking at 10:20 UTC on March 07, associated with SIDC Sunspot Group 811 (NOAA Active Region 4385, magnetic type alpha). There are currently five numbered active regions on the solar disk. The most complex ones have a beta magnetic type. SIDC Sunspot Group 812 (NOAA Active Region 4386, magnetic type beta) is currently rotating across the west limb. 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 slow, wide Coronal Mass Ejection (SIDC CME 637) was observed in LASCO/C2 and LASCO/C3 coronagraph imagery, lifting off the east limb around 20:55 UTC on March 06. It is likely associated with eruptive activity on the east 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 equatorial, negative polarity coronal hole (SIDC Coronal Hole 149), which crossed the central meridian on March 04. The solar wind speed increased from 350 km/s to 470 km/s. The interplanetary magnetic field increased from 5 nT to 13 nT. The Bz component varied between -8 nT and 8 nT but was mostly negative. 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 influence of the high-speed stream from SIDC Coronal Hole 149 and the probable arrival of a high-speed stream from the northern, mid-latitude, negative polarity coronal hole (SIDC Coronal Hole 142).

Геомагнетизм

Geomagnetic conditions globally were initially quiet (NOAA Kp 1 to 2) during the last 24 hours, increasing then to unsettled (NOAA Kp 3) and reaching active levels (NOAA Kp 4+ ) between 00:00 UTC and 03:00 UTC on March 07. Geomagnetic conditions locally reached unsettled levels (K Bel 3) between 22:00 UTC on March 06 and 03:00 UTC on March 07 and later between 07:00 UTC and 10:00 UTC. Active to minor storm conditions (NOAA Kp 4 to 5) are expected over the next 24 hours, under the influence of the high-speed stream from SIDC Coronal Hole 149 and the probable arrival of a high-speed stream from the northern, mid-latitude, negative polarity coronal hole (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 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.
