Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was low over the past 24 hours, with several C-class flares recorded. The largest flare was a C1.2 flare (SIDC Flare 6622), peaking at 14:22 UTC on January 9, associated with SIDC Sunspot Group 754 (NOAA Active Region 4336; magnetic type beta-gamma). There are currently four numbered active regions on the visible solar disk. SIDC Sunspot Group 754 (NOAA Active Region 4336) remains the most complex active region on the disk and was the main driver of the flaring activity observed over the past 24 hours. A new region emerged and was numbered in the southeastern hemisphere (SIDC Sunspot Group 759, NOAA Active Region 4339; S16E02; magnetic type beta), but it remained quiet. SIDC Sunspot Group 757 (NOAA Active Region 4337; magnetic type beta) is approaching the west limb. Solar flaring activity is expected to remain low over the next 24 hours, with C-class flares very likely and a small chance of M-class flares.

Vyhazování koronální hmoty

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images over the past 24 hours.

Koronální díra

A small equatorial negative polarity coronal hole (SIDC Coronal Hole 136) has started to cross the central meridian today, on January 10.

Solární bouře

Over the past 24 hours, solar wind parameters (ACE and DSCOVR) reflected the ongoing influence of the high-speed stream. The interplanetary magnetic field magnitude decreased from about 14 nT to current values below 9 nT. The solar wind speed decreased from about 560 km/s to 480 km/s. The southward component of the interplanetary magnetic field fluctuated between -8 nT and 9 nT. The magnetic field orientation was predominantly in the negative sector (field directed toward the Sun). Solar wind conditions are expected to remain slightly elevated over the next day, with a chance of a weak enhancement late on January 10 to early on January 11 due to possible ICME arrivals associated with the CMEs that lifted off the solar surface at around 06:24 UTC on January 8 (SIDC CME 620) and around 17:00 UTC on January 8 (SIDC CME 622).

Geomagnetismus

Geomagnetic conditions reached active levels globally (NOAA Kp = 4-) between 06:00 and 09:00 UTC on January 10. Locally over Belgium, quiet to unsettled conditions were observed (K-Bel = 1 to 3). Mostly unsettled to active geomagnetic conditions are expected over the next days, with a chance of isolated minor to moderate storm periods from late on January 10 to early on January 11, due to possible ICME arrivals associated with the CMEs that lifted off the solar surface at around 06:24 UTC on January 8 (SIDC CME 620) and around 17:00 UTC on January 8 (SIDC CME 622).

Úrovně protonového toku

The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at background levels over the past 24 hours and is likely to remain so over the next 24 hours.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux, as measured by the GOES-18 and GOES-19 satellites, remained below the 1000 pfu threshold over the past 24 hours. The greater than 2 MeV electron flux may exceed the 1000 pfu threshold over the next 24 hours. The electron fluence was at normal levels and is expected to be at normal to moderate levels over the next 24 hours.
