Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was high over the past 24 hours, with 3 M-class flares identified. SIDC Sunspot Group (SG) 709 (NOAA Active Region 4294, Beta magnetic configuration) emitted all the M-class and all but one of the C-class flaring activity of the past 24 hours, although it remains partially obscured by the eastern solar limb. The M-class flares of the past 24 hours were SIDC flares 6228 (an M5.9 on 28 Nov at 22:22 UTC), 6230 (an M1.6 on 29 Nov at 00:02), and 6232 (an M1.5 on 29 Nov at 04:20 UTC). SIDC SG 709 is expected to increase its activity in the next 24 hours as a larger portion of it will become visible from L1. M-class flares are expected and there is still a small chance of an X-class flare.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours.

Wiatr słoneczny

Over the past 24 hours, solar wind parameters (ACE and DSCOVR) continued to reflect the waning influence of a high-speed stream (HSS). The solar wind speed gradually decreased from about 680 km/s to 600 km/s. The interplanetary magnetic field (B) varied between 3 and 7 nT and its North- South component (Bz) fluctuated between -6 and 5 nT. The SW speed is expected to continue its slow decline and the magnetic field is expected continue at similar levels in the next 24 hours.

Geomagnetyzm

The global geomagnetic conditions fluctuated between unsettled and active values (NOAA Kp 3- to 4) over the past 24 hours. During the same period the local conditions registered quiet and unsettled values (K BEL 2 to 3). A similar pattern is expected in the next 24 hours, both for the global and local conditions.

Poziomy przepływu protonów

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 in the next 24 hours. Nevertheless there is a small chance that a proton event, associated with SIDC SG 709, might occur during the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by GOES-19, was above the 1000 pfu threshold during the past 24 hours with a peak value of 15000 pfu on 29 Nov at 04:30 UTC. The electron flux is expected to feature a further increase over the next day. The 24-hour electron fluence was at moderate levels during the past 24 hours. It is expected to increase further in the next 24 hours and reach high levels.
