Сонячно-активні області та спалахи

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C1.3 flare (SIDC Flare 7036) peaking on February 15 at 07:27 UTC, which was produced by SIDC Sunspot Group 793. A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 795 (NOAA Active Region 4377) is 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.

Корональні викиди маси

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

Корональні діри

SIDC Coronal Hole 150 (equatorial coronal hole with a negative polarity) started crossing the central meridian on February 14. A high-speed stream associated with this coronal hole is expected to arrive at Earth early on February 17.

Сонячний вітер

Over the past 24 hours the solar wind parameters came under the influence of a high-speed stream associated with SIDC Coronal Hole 146. The solar wind speed gradually rose from 370 km/s to 722 km /s. The total interplanetary magnetic field ranged from 5 to 15 nT, with the Bz reaching a minimum of -14 nT. The phi-angle was mainly in the positive sector (directed away from the Sun), with a period between 16:00 UTC on February 14 and 00:10 UTC on February 15. In the next 24 hours solar wind conditions are expected to remain enhanced.

Геомагнетизм

The geomagnetic conditions reached minor storm condition globally and locally (Kp 5+ & K BEL 5) in the last 24 hours. Active to minor storm conditions are expected over 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.
