Сонячно-активні області та спалахи

Solar flaring activity was moderate with two M-class flares detected during the past 24 hours. NOAA Active Region (AR) 3612 (magnetic type Alpha, Catania group 15) produced an M2 today at 03:32 UTC. NOAA AR 3614 (magnetic type Alpha, Catania group 13) produced the second M-class flare, an M1 today at 04:14 UTC. For the next 24 hours, more M-class flaring activity is expected from the two AR mentioned above and there is a small chance of a proton event.

Корональні викиди маси

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

Сонячний вітер

The Solar Wind (SW) conditions were typical of the slow SW regime during the last 24 hours. The SW speed gradually dropped from 420 to 260 km/s, while the total interplanetary magnetic field (Bt) was up to 8 nT. The North-South magnetic component (Bz) ranged between -1 and 5 nT, while the interplanetary magnetic field phi angle was predominantly 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 globally and locally quiet (NOAA Kp 0 to 2 and K BEL 0 to 1) during the last 24 hours. They are expected to remain 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 low levels during the past 24 hours and is expected to remain at these levels for the following 24 hours.
