Сонячно-активні області та спалахи

Solar flaring activity was low with eight C-class flares detected during the past 24 hours. The brightest flare was an C9.5 on 27 Nov at 10:20 UTC from the newly-emerged SIDC Sunspot Group 326 (NOAA active region 3911). SIDC Sunspot Group 322 (NOAA active region 3905) produced three flares, while SIDC Sunspot Group 302 (NOAA active region 3910) emitted two during the last 24 hours. The rest were produced by SIDC Sunspot Group 298 (NOAA active region 3901) and Sunspot Group 323 (NOAA active region 3906). M-class flaring activity is expected in the next 24 hours, mostly from SIDC Sunspot Groups 302, 322, 323, and 326. Additionally, there is a chance of an X-class flare in the next 24 hours mostly from SIDC Sunspot Group 302.

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 between from 300 km/h and 400 km/h in the last 24 hours. The total interplanetary magnetic field (Bt) ranged between 2 and 7 nT and its North-South component (Bz) registered values between -6 and 6 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 and locally quiet (NOAA Kp 1- to 2 and K BEL 0 to 2). In the next 24 hours they are expected to remain at quiet 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. However, there is the possibility of a proton even in the next 24 hours.

Потоки електронів на геостаціонарній орбіті

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