太陽活動區和耀斑

Solar flaring activity was moderate over the past 24 hours, with 2 M-class flares identified. The largest flare was a M1.4 flare (SIDC Flare 7016) peaking on February 11 at 13:12 UTC, which was produced by SIDC Sunspot Group 784 (NOAA Active Region 4366). The second largest flare was M1.4 flare (SIDC Flare 7022) peaking on February 12 at 02:40 UTC probably produced by SIDC Sunspot Group 784 after it passed the West limb rotating off the visible solar disk. A total of 7 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 790 (NOAA Active Region 4373) was the most magnetically complex (Beta) region on disk. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares likely and a small chance for M-class flares.

日冕物質拋射

No Earth directed Coronal Mass Ejections (CMEs) were observed in the past 24 hours.

太陽風

Slow solar wind conditions were recorded over the past 24 hours. The solar wind speed ranged from 371 km/s to 480 km /s. The total interplanetary magnetic field ranged from 4 to 8 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.

地磁

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

質子通量水平

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.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux, as measured by the GOES-18 and GOES-19 satellites remained below the threshold level in the last 24 hours. The electron flux is expected to remain below the threshold in the coming 24 hours. The 24h electron fluence is presently at normal level, and it is expected to remain so in the next 24 hours.
