太陽活動區和耀斑

Solar flaring activity was moderate over the past 24 hours. The largest flare was a M3.3 flare (SIDC Flare 6631) peaking on January 11 at 23:14 UTC, originated from a region from behind the east limb. A total of 4 numbered sunspot groups are currently on the disk, all having alpha or beta magnetic configuration and have produced only C-class flaring. 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.

日冕物質拋射

No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images. The halo CME detected in SOHO/LASCO-C2 data from 23:36 UTC 11 JAN 2026, is backsided and not expected to arrive to the Earth.

太陽風

Solar wind conditions were slightly elevated with speeds around 540 km/s. The interplanetary magnetic field was around 10nT, with the Bz reaching a minimum value of -10 nT. Solar wind conditions are expected to remain slightly elevated due to the ongoing ICME passage, and the possible arrival of high-speed streams from negative polarity coronal holes (SIDC Coronal Hole 137 and SIDC Coronal Hole 142).

地磁

Geomagnetic conditions reached minor storm levels globally and locally (Kp 5, K5) between 12:00 and 21:00 UTC on January 11 Mostly unsettled to active geomagnetic conditions are expected over the next day due to the ongoing ICME passage and possible HSS arrival.

質子通量水平

The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux exceeded slightly the 1000 pfu threshold on 11 JAN between 21:35 UTC and 12 JAN 01:30 UTC and is currently slightly above the threshold since 10:45 UTC. The greater than 2 MeV electron flux is expected to have short crossings over the 1000 pfu threshold over the next 24 hours. The electron fluence was at normal levels and is expected to be at normal levels over the next 24 hours.
