Сонячно-активні області та спалахи

Solar flaring activity was low over the past 24 hours. The largest flare was a C8.3 flare (SIDC Flare 6572) peaking on January 03 at 17:29 UTC, which was produced by SIDC Sunspot Group 745 (NOAA Active Region 4325). There are currently 7 numbered regions on the disk. SIDC Sunspot Group 745 (NOAA Active Region 4325, Beta configuration) is the largest region. SIDC Sunspot Group 744 (NOAA Active Region 4324, Beta magnetic configuration) also produced C-class flares but continued to reduce in size over the period. SIDC Sunspot Group 751 (NOAA Active Region 4333, beta magnetic configuration exhibited flux emergence. SIDC Sunspot Group 709 (NOAA Active Region 4323) was stable. A new region rotated over the west limb (S08E86) and was numbered SIDC Sunspot Group 754. SIDC Sunspot Groups 752 and 747 decayed over the period. The remaining regions are simple and mostly quiet. Solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares expected and a chance for X-class flares.

Корональні викиди маси

No new Earth directed Coronal Mass Ejections (CMEs) have been detected.

Сонячний вітер

Over the past 24 hours, the solar wind parameters indicated the waning influence of the high speed stream and a possible weak ongoing ICME signature. The solar wind speed decreased from around 700 kms to around 410 km/s. The total magnetic field decreased steadily from 7nt to 4nT. Bz had a minimum of -6 nT and was predominantly positive. The interplanetary magnetic field phi angle was mostly in the negative sector (directed towards the Sun). Enhanced solar wind conditions are expected from late on January 04 due to the arrival of a CME observed late on January 01.

Геомагнетизм

Over the past 24 hours, the geomagnetic conditions were at quiet to unsettled levels globally (NOAA Kp 3) and locally (K BEL 3). Quiet conditions are expected for January 04, with active to minor storm conditions possible from early on January 05, due to the possible CME arrival.

Рівні потоку протонів

The greater than 10 MeV proton flux was below the 10 pfu threshold over the past 24 hours. It is expected to remain below this threshold level over the next 24 hours.

Потоки електронів на геостаціонарній орбіті

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