Päikese aktiivsed piirkonnad ja pursked

Solar flaring activity was moderate over the past 24 hours, with 4 M-class flares identified. SIDC Sunspot Group 322 (NOAA active region 3905) produced two of those flares, an M2.0 (SIDC flare 2717) on 25 Nov at 12:12 UTC and an M1.0 (SIDC flare 2718) on 25 Nov at 16:36 UTC. The third M-class flare (SIDC flare 2714) was emitted by an Active Region (AR) at E89N16 on 25 Nov at 17:07 UTC. The forth was an M1.9 that peaked on 25 Nov at 20:54 UTC (SIDC flare 2715) and is associated with the SIDC Sunspot Group 298 (NOAA Active Region 3901). More M-class flaring activity is expected in the next 24 hours, mostly from the pair of SIDC Sunspot Groups 322 and 323 (NOAA AR 3906). Additionally, there is a chance of an X-class flare in the next 24 hours also from the same pair of AR.

Krooniaine massiline väljavool

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

Päikesetuul

The Solar Wind (SW) conditions were typical of the slow SW regime during the last 24 hours. The SW speed gradually dropped from 450 km/h to 350 km/h in the last 24 hours. The total interplanetary magnetic field (Bt) varied between 1 and 8 nT and its North-South component (Bz) ranged between -7 and 7 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.

Geomagnetism

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

Prootoni voo tasemed

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.

Elektronivoog geostatsionaarsel orbiidil

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.
