Zonnevlekkengebieden en zonnevlammen

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C6.0 flare (SIDC Flare 7034) peaking on February 14 at 11:13 UTC, which was produced by SIDC Sunspot Group 762 (NOAA Active Regions 4342, 4374). A total of 9 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 762 (NOAA Active Region 4374) is 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 likely and a small chance for M-class flares.

Coronale massa uitstoten

A northwest directed Coronal Mass Ejection (CME) was seen in LASCO-C2 data at 09:12 UTC on February 13. This CME is associated with a M1.0 flare (SIDC Flare 7028) peaking on February 13 at 08:58 UTC near the centre of the solar disk. Analysis suggests a possible glancing blow arrival at Earth early on February 16. No other Eart-directed CMEs were observed in the available coronagraph imagery.

Coronale gaten

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 early on February 16.

Zonnewind

The solar wind speed ranged from 404 km/s to 528 km /s. The total interplanetary magnetic field ranged from 4 to 10 nT, with the Bz reaching a minimum of -8 nT. The phi-angle was in the negative sector (directed towards the Sun) until 20:57 UTC on February 13 when it switched to the positive sector. In the next 24 hours a slow solar wind regime is expected.

Geomagnetisme

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.

Proton flux niveaus

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.

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux, as measured by the GOES-19 satellites was above the 1000 pfu threshold between 16:45 UTC and 17:55 UTC on February 13 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.
