Slunečně aktivní oblasti a vzplanutí

A total of 9 numbered sunspot groups were identified on the disk over the past 24 hours. There were two M-class flares in the last 24 hours. Both flares occurred close in time, the first one was an M1.8 peaking on February 8 at 11:18 UTC and the second one was an M1.7 on February 8 at 11:43 UTC. Both were produced by SIDC Sunspot Group 784 (NOAA Active Region 4366) currently located at N13W45 with a Beta-Gamma-Delta magnetic configuration. This region remains the largest and most complex on disk. Solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares likely.

Vyhazování koronální hmoty

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

Koronální díra

There are two equatorial coronal holes on the equator and on the western hemisphere: SIDC Coronal Hole 136 and 149 (equatorial coronal holes with a negative polarity). SIDC Coronal Hole 142 (mid-latitude coronal hole with a negative polarity) is also on the west, but at higher latitudes.

Solární bouře

The solar wind speed at Earth is at 450 km/s. The interplanetary magnetic field is around 6 nT. In the coming 24 hours, the solar wind speed is expected to increase due to the influence of coronal hole associated high speed streams (from SIDC 149 and probably also 142).

Geomagnetismus

Geomagnetic conditions have reached active periods at planetary levels in the last 24 hours (Kp up to 4), and only unsettled locally (K_Bel up to 3). Similar unsettled to active conditions can be expected for the next 24 hours.

Úrovně protonového toku

The greater than 10 MeV proton flux remained below the 10 pfu threshold in the last 24 hours. Similar conditions can be expected for the next 24 hours.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux as measured by GOES 19 was above the threshold between 12:00 UTC and 23:00 UTC on 7 February and GOES 18 between 14:00 UTC on 7 February and 02:00 UTC on 8 February. The flux is expected to remain below the threshold for the next 24 hours. The 24-hour electron fluence was at normal levels and is expected to remain so.
