Сонячно-активні області та спалахи

Solar flaring activity was moderate over the past 24 hours, with 2 M-class flares identified. The largest flare was an M1.2 flare (SIDC Flare 7008) peaking on February 11 at 00:09 UTC. The second-largest flare was an M1.1 flare (SIDC Flare 7009) peaking on February 11 at 00:44 UTC. Both were produced by SIDC Sunspot Group 784 (NOAA Active Region 4366. A total of 10 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 784 (NOAA Active Region 4366) was the largest region on disk, the most magnetically complex (Beta-Gamma-Delta) and produced most of the flaring activity in the last 24 hours. This region has rotating over the western limb off the visible solar disk. 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 past 24 hours. A filament eruption was seen near the centre of the visible solar disk around 17:16 UTC on February 10 in SDO/AIA 304 and 193. No associated CME was seen in the coronagraph images.

Сонячний вітер

Slow solar wind conditions were recorded over the past 24 hours. The solar wind speed ranged from 430 km/s to 520 km /s. The total interplanetary magnetic field ranged from 5 to 9 nT, with the Bz reaching a minimum of -7 nT. The phi-angle was mainly in the negative sector (directed towards the Sun), with periods in the positive sector. In the next 24 hours a slow solar wind regime is expected.

Геомагнетизм

The geomagnetic conditions reached active condition globally (Kp 4) and minor storm conditions locally (K BEL 5) in the last 24 hours. Quiet to unsettled conditions are expected in the next 24 hours.

Рівні потоку протонів

The greater than 10 MeV GOES proton flux was at background levels and is expected to remain at background levels over the next 24 hours.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux, as measured by the GOES-18 satellite was above the 1000 pfu threshold between 18:40 UTC and 22:55 UTC on February 10. The 2 MeV electron flux is expected to cross the threshold again during the next 24 hour. The 24-hour electron fluence was at moderate levels and is expected to return to normal levels over the next 24 hours.
