Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate over the past 24 hours. The largest flare was a M1.6 flare (SIDC Flare 2677) peaking on November 22 at 15:46 UTC, which was produced by SIDC Sunspot Group 322 (NOAA Active Region 3905). A new region also rotated over the south-east solar limb, below SIDC Sunspot Group 322, and was numbered as SIDC Sunspot Group 323 (NOAA Active Region 3906), which also produced an M1 flare (SIDC Flare 2685) peaking on November 22 at 22:15 UTC. These two regions were responsible for most of the flaring activity, while the SIDC Sunspot Group 298 (NOAA Active Region 3901) also produced C-class flares. The solar flaring activity is expected to be moderate over the next 24 hours, with C-class flares expected, M-class flares likely and a chance for X-class flares.

Koronalny wyrzut masy

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

Wiatr słoneczny

Over the past 24 hours the interplanetary magnetic field ranged between 6 and 10nT, with a minimum Bz of -8 nT. The solar wind speed ranged between 360 km/s and 430 km/s. The interplanetary magnetic field phi angle was mostly in the negative sector (directed towards the Sun). The solar wind speed may become slightly elevated over the next 24 hours due to the possible high-speed stream influence, associated with SIDC Coronal Hole 80, which began to cross the central meridian on November 20.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were mostly quiet to unsettled, with one period of active conditions (NOAA KP 4-). Generally quiet to unsettled geomagnetic conditions are expected for the next 24 hours, with possible isolated active conditions due to any high- speed stream influence.

Poziomy przepływu protonów

The greater than 10 MeV GOES proton flux was above the 10 pfu threshold at the start of the period but was continually decreasing and returned below the threshold from 18:45 UTC November 22. The greater than 10 MeV GOES proton is currently at nominal levels and is expected to remain below the 10 pfu threshold over the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as measured by GOES 18 was below the 1000 pfu threshold and is expected to remain below this threshold over the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so in the next 24 hours.
