Päikese aktiivsed piirkonnad ja pursked

Solar flaring activity was moderate over the past 24 hours, with an M1.0 flare emitted from SIDC Sunspot Group 298 (NOAA Active Region [AR] 3901) on 27 Nov at 12:46 UTC. C-class flares of C6.0 or brighter were produced by: SIDC Sunspot Group 302 (NOAA AR 3910), SIDC Sunspot Group 322 (NOAA AR 3905), NOAA AR 3912, and an yet-unnamed AR at E90S05. More M-class flaring activity is expected in the next 24 hours, mostly from any of SIDC Sunspot Groups 302, 322, or 323 (NOAA AR 3906). Additionally, there is a chance of an X-class flare in the next 24 hours also from one of those three AR.

Krooniaine massiline väljavool

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

Krooniauk

A very small equatorial corona hole with positive polarity is currently crossing the solar central meridian. It is expected to have a minor effect to Earth's geomagnetic conditions on 1 Dec.

Päikesetuul

The Solar Wind (SW) conditions remained in the slow SW regime during the last 24 hours. The SW speed varied between 350 km/h and 450 km/h in the last 24 hours. The total interplanetary magnetic field (Bt) ranged between 5 and 8 nT and its North-South component (Bz) registered values between -6 and 7 nT. The interplanetary magnetic field phi angle was 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 (NOAA Kp 1- to 2+ and K BEL 1 to 2). In the next 24 hours they are expected to remain 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.
