Сонячно-активні області та спалахи

Solar flaring activity was moderate during the last 24 hours, with two M1 flares produced by NOAA Active Region (AR) 3380 (magnetic type Beta, Catania group 95) yesterday 16:24 UTC and by NOAA AR 3390 (magnetic type Beta) today 08:22 UTC. C-class flares brighter than C4 were also produced in the last 24 hours: a C6 and a C5 by NOAA AR 3379 (magnetic type Alpha, Catania group 91) and a C5 by NOAA AR 3380. For the next 24 hours isolated M-class flares are very likely, with a small chance of an X-flare.

Корональні викиди маси

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

Сонячний вітер

The Solar Wind (SW) conditions resemble the slow SW regime. The SW speed gradually increased from 360 km/s to about 540 km/s in the last 24 hours. The total interplanetary magnetic field (Bt) varied between 2 and 9 nT and its North-South component (Bz) ranged between -7 and 9 nT. The interplanetary magnetic field phi angle was directed predominantly away from the Sun during the past 24 hours. The SW conditions are expected to remain at similar levels in the next 24 hours.

Геомагнетизм

Geomagnetic conditions were globally and locally at quiet to unsettled levels (NOAA Kp and K BEL 1 to 3) during the past 24 hours. They are expected to remain at the same levels both locally and globally in the next 24 hours.

Рівні потоку протонів

The greater than 10 MeV proton flux dropped below the 100 pfu threshold level yesterday at 12:05 UTC. However, it remains above the the 10 pfu threshold and it is expected to stay above this level for the next several hours.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, exceeded momentarily the 1000 pfu alert level yesterday at 14:45 UTC and remain close to this limit until about 19:15 UTC. For the next 24 hours, it is expected to increase again but remain below the threshold level. The 24h electron fluence is increased but remains at nominal levels and is expected to remain so during the next 24 hours.
