Сонячно-активні області та спалахи

Solar flaring activity was moderate over the past 24 hours, with 1 M-class flare identified. The largest flare was a M1.0 flare (SIDC Flare 7028) peaking on February 13 at 08:58 UTC, which was produced by SIDC Sunspot Group 790 (NOAA Active Region 4373). A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 790 (NOAA Active Region 4373) and SIDC Sunspot Group 762 (NOAA Active Region 4374) are the largest and most magnetically complex (Beta) regions on 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 available coronagraph imagery over the past 24 hours. An eruption was observed in SDO/AIA 193 at 09:40 UTC on February 13 associated with a M1.0 flare (SIDC Flare 7028) peaking on February 13 at 08:58 UTC near the center of the solar disk. We’re waiting for new coronagraph images to see if there is a CME associated with this eruption.

Корональні діри

SIDC Coronal Hole 146 (equatorial coronal hole with a positive polarity) started crossing the central meridian on February 12. (Other crossing times : January 24, January 16). A high-speed stream associated with this coronal hole is expected to arrive at Earth late on February 15.

Сонячний вітер

Slow solar wind conditions were recorded over the past 24 hours. The solar wind speed ranged from 350 km/s to 454 km /s. The total interplanetary magnetic field ranged from 4 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 quiet to unsettled conditions locally (K BEL 1-3) 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 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.
