Solaraktive Regionen und Flares

Solar flaring activity was moderate over the past 24 hours, with 2 M-class flares identified. The largest flare was a M2.8 flare (SIDC Flare 6993) peaking on February 09 at 02:27 UTC, which was produced by SIDC Sunspot Group 784 (NOAA Active Region 4366). A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 784 (NOAA Active Region 4366) is 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 is about to rotate 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.

Koronaler Massenauswurf

No Earth directed CMEs were observed in the past 24 hours.

Koronale Löcher

SIDC Coronal Hole 137 (mid-latitude coronal hole with a negative polarity) first reached the central meridian on February 09 and is now positioned on the eastern side of the Sun. (Other crossing times : December 15, November 18)

Sonnenwind

The solar wind speed at Earth is around 420 km/s. The total interplanetary magnetic field ranged from 6 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.

Geomagnetismus

The geomagnetic conditions were quiet to unsettled globally and locally (Kp 1-3 & K BEL 1-3) in the last 24 hours. Quiet to unsettled conditions are expected in the next 24 hours.

Protonenflusswerte

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.

Elektronenflüsse im geostationären Orbit

The greater than 2 MeV electron flux, as measured by the GOES-19 satellite was above the 1000 pfu threshold at the start of the period until November at 20:30 UTC. The GOES-18 satellite was above the 1000 pfu threshold between 15:10 UTC and 01:45 UTC on November 08. The 2 MeV electron flux is expected to cross the threshold again during the next 24 hour. The 24-hour electron fluence was at normal levels and is expected to remain at normal levels over the next 24 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 120, basierend auf 06 Stationen.
