Сонячно-активні області та спалахи

Solar flaring activity was low but frequent during the past 24 hours. Most of the activity was produced by a group of Active Regions (AR) consisting of NOAA AR 3490 (magnetic configuration B, Catania group 55), 3492 (magnetic configuration Alpha, Catania group 58), and 3502 (magnetic configuration Beta, Catania group 64). The brightest flares were four C-class flares produced by NOAA AR 3490, 3502, and an yet-unnamed AR currently rotating into view at S16. Further C-class flaring activity is expected in the next 24 hours, mostly from the AR mentioned above. Additionally there is a chance for an isolated M-class flare, mostly from NOAA AR 3492 or one of its neighbours.

Корональні викиди маси

A Corona Mass Ejection associated with a filament eruption can be seen in LASCO-C2/SOHO images starting from 06:48 UTC, today. Based on the location and extent of the filament, an Earth-directed component is possibly present. If geo-effective, it is expected to arrive at Earth's atmosphere the first half of 1 Dec.

Сонячний вітер

The Solar Wind (SW) conditions returned to a slow SW pattern during the last 24 hours. The SW speed dropped from 560 to 430 km/s, while the total interplanetary magnetic field (Bt) was fairly stable between 3 and 6 nT. The North-South magnetic component (Bz) varied between -4 and 5 nT, while the interplanetary magnetic field phi angle was mostly directed away from the Sun in the past 24 hours. The SW conditions are expected to remain in the slow SW regime for the next 24 hours.

Геомагнетизм

Geomagnetic conditions were quiet globally (NOAA Kp 1- to 2+) and quiet to unsettled locally (K BEL 1-3) during the last 24 hours. They are expected to be at quiet levels both globally and locally in the next 24 hours.

Рівні потоку протонів

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was at nominal levels during the last 24 hours and is expected to remain below this threshold during the next 24 hours. The 24h electron fluence was at very low levels during the past 24 hours and is expected to remain at these levels for the following 24 hours.
