Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was low over the past 24 hours. The largest flare was a C6.5 flare (SIDC Flare 6560) peaking on January 02 at 00:17 UTC, which was produced by newly emerged SIDC Sunspot Group 751 (NOAA Active Region 4333). This region produced multiple C-class flares. There are currently 8 numbered regions on the disk. SIDC Sunspot Group 744 (NOAA Active Region 4324) produced a long duration C6.2 flare, peaking on January 01 at 17:59 UTC. This region has decayed over the period and is now Beta-Delta magnetic configuration. SIDC Sunspot Group 745 (NOAA Active Region 4325, Beta-Gamma configuration) is the largest region on disk and also produced low level C-class flares. SIDC Sunspot Group 735 (NOAA Active Region 4317) continued to produce some C-class flare from beyond the limb. A returning active region (SIDC Sunspot Group 722) has also rotated onto disk (S16E83). A new region emerged in the north-west quadrant and was numbered SIDC Sunspot Group 752. The remaining regions are simple and mostly quiet or in decay. 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.

Vyhazování koronální hmoty

A Coronal Mass Ejection (CME) directed to the north-east was first seen in LACSCO-C2 data from 18:48 UTC on January 01. This was associated with the C6.2 flare from SIDC Sunspot Group 744 (NOAA Active Region 4324), with peak time17:59 UTC. This CME is may glancing blow at Earth from early on January 05.

Solární bouře

Over the past 24 hours, the solar wind parameters showed and ongoing weak high speed stream influence. The solar wind speed ranged between 450 and 580 km/s. The total magnetic field ranged between 2 and 9 nT, and Bz had a minimum of -7 nT. The interplanetary magnetic field phi angle was in the negative sector (directed towards the Sun). Disturbed solar wind conditions are expected from early on January 03, due to the arrival of a CME from December 31.

Geomagnetismus

Over the past 24 hours, the geomagnetic conditions were at quiet to unsettled levels globally, with one period of active conditions (NOAA Kp 1 to 4), and at quiet to unsettled levels locally (K BEL 1 to 3). Active conditions are expected for January 02, with minor to moderate storm conditions expected from January 03, due to the possible CME arrival.

Úrovně protonového toku

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.

Elektronové toky na geostacionární oběžné dráze

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