Сонячно-активні області та спалахи

Solar flaring activity was low over the past 24 hours, with several C-class flares recorded. The largest flare was a C3.8 flare (SIDC Flare 6626), peaking at 20:14 UTC on January 10, and associated with SIDC Sunspot Group 757 (NOAA Active Region 4337; magnetic type beta). There are currently four numbered active regions on the visible solar disk. SIDC Sunspot Group 754 (NOAA Active Region 4336; magnetic type beta-gamma-delta) remains the most complex active region on the disk but produced only low-level C-class flare. SIDC Sunspot Group 757 (NOAA Active Region 4337) is expected to rotate over the west limb in the coming hours. Low flaring activity was also produced by SIDC Sunspot Group 759 (NOAA Active Region 4339; magnetic type beta). Solar flaring activity is expected to remain low over the next 24 hours, with C-class flares very likely and a chance of M-class flares.

Корональні викиди маси

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

Сонячний вітер

At the beginning of the period, solar wind parameters reflected the waning influence of a high-speed stream. The solar wind speed decreased from about 480 km/s to 450 km/s, while the interplanetary magnetic field remained below 8 nT. A fast forward shock was detected in the solar wind data (ACE and DSCOVR) at 19:36 UTC on January 10. The interplanetary magnetic field jumped from about 6 nT to 16 nT, briefly reaching values up to 20 nT, while the solar wind speed jumped from approximately 475 km/s to 580 km/s. The north–south component of the interplanetary magnetic field (Bz) reached a minimum value of -20 nT. This disturbance is likely due to the ICME arrival associated with the partial halo CME that lifted off the solar surface at around 17:00 UTC on January 8 (SIDC CME 622). Solar wind conditions are expected to remain slightly elevated due to the ongoing ICME passage, with a chance of a weak enhancement on January 13 due to the possible arrival of high-speed streams from negative polarity coronal holes (SIDC Coronal Hole 137 and SIDC Coronal Hole 142).

Геомагнетизм

Geomagnetic conditions reached moderate storm levels globally (NOAA Kp = 6, 6- ) and minor storm levels locally over Belgium (K-Bel = 5) between 18:00 and 00:00 UTC on January 10, following an ICME arrival. Mostly unsettled to active geomagnetic conditions are expected over the next day due to the ongoing ICME passage.

Рівні потоку протонів

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.

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 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.
