Сонячно-активні області та спалахи

Solar flaring activity was high during the last 24 hours, with four M-class flares detected during the past 24 hours. Two of those flares were emitted from an Active Region (AR) just behind the East solar limb, an M9.4 at 25 Nov 07:42 UTC (SIDC Flare 2709) and an M1.1 at 24 Nov 20:22 UTC (SIDC Flare 2711). The other two M-class flares were associated with NOAA AR 3906, an M1.8 at 25 Nov 04:53 UTC (SIDC Flare 2710) and an M1.1 at 25 Nov 01:59 (SIDC Flare 2709). The AR behind the East limb is expected to continue its M-class flaring activity and possibly produce X-class flare(s) in the next 24 hours. NOAA AR 3906 is expected to continue its M-class flaring activity and there is a small change for an X-class flare during the next 24 hours.

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 varied from 330 km/h to about 470 km/h in the last 24 hours. The total interplanetary magnetic field (Bt) varied between 4 and 9 nT and its North-South component (Bz) ranged between -8 and 8 nT. The interplanetary magnetic field phi angle was predominately directed towards the Sun during the past 24 hours. The solar wind speed is expected to remain in the slow SW regime during the next 24 hours.

Геомагнетизм

During the last 24 hours geomagnetic conditions were globally quiet to active (Kp 2 to 4-) and locally quiet to unsettled (K BEL 1 to 3). In the next 24 hours they are expected to be at quiet to unsettled levels both globally and locally.

Рівні потоку протонів

The greater than 10 MeV proton flux, as measured by the GOES-18 satellite, was at nominal levels over the past 24 hours and is likely to remain so.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux as measured by GOES 18 was below the 1000 pfu threshold and is expected to remain below this threshold over the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so in the next 24 hours.
