Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate over the past 24 hours with four M-class flares emitted on the second half of 29 Nov. SIDC Sunspot Group (SG) 709 (NOAA Active Region 4294, Beta magnetic configuration) was the source of three of those flares, while the fourth came from a yet-unnamed region at N20E90. More specifically the brightest flare of the past 24 hours was an M2.8 that peaked at 16:07 UTC and was located at N20E90. SIDC SG 709 produced an M1.1 at 13:16 UTC, an M1.4 at 20:14 UTC, and an M1.4 at 21:48 UTC. In the next 24 hours more M-class flaring activity is expected from the two locations mentioned above. There is also a chance of X-class flare(s) from either location.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours. A CME seen in LASCO-C2 images as launched on 29 Nov at 05:48 UTC is not expected to affect the Earth.

Wiatr słoneczny

Over the past 24 hours, the Solar Wind (SW) parameters (ACE and DSCOVR) continued to gradually return to a slow SW regime. The SW speed gradually decreased from about 650 km/s to 550 km/s. The interplanetary magnetic field (B) varied between 1 and 8 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

During the last 24 hours geomagnetic conditions were globally and locally quiet to active (NOAA Kp 2+ to 4 and K BEL 2 to 4). In the next 24 hours they are expected to be at quiet to unsettled levels both globally and locally.

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 23000 pfu on 29 Nov at 16:40 UTC. The electron flux is expected to feature a further increase over the next day. The 24-hour electron fluence crossed to high levels on 29 Nov at 18:25 UTC. It is expected to marginally increase and remain at high levels for the next 24 hours.
