Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was low over the past 24 hours, with only four C1 flares identified. SIDC Sunspot Group 423 (NOAA Active Region [AR] 4012, Beta-Gamma magnetic configuration) and SIDC Sunspot Group 427 (NOAA AR 4016, Beta-Gamma magnetic configuration) remain the most complex AR on disk but only the first of the two produced a C-class flare in the past 24 hours. Most of the activity (two C1) was produced by a yet-unnamed AR rotating into Earth's view close to the solar equator. C-class flaring activity is expected in the next 24 hours, although there is chance of isolated M-class flaring.

Vyhazování koronální hmoty

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

Solární bouře

The Solar Wind (SW) conditions were typical of the slow SW regime during the last 24 hours. The SW speed fluctuated between 340 and 470 km/s, while the interplanetary magnetic field (B) ranged between 3 to 10 nT in the last 24 hours. Its North-South component (Bz) registered values between -7 and 10 nT during the same period. The SW conditions are expected to remain in the slow SW regime over the next 24 hours.

Geomagnetismus

Geomagnetic conditions were both globally and locally quiet to unsettled (NOAA Kp 0+ to 3+ and K BEL 1 to 3) during the past 24 hours. In the next 24 hours they are expected to remain at this level of activity.

Úrovně protonového toku

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 in the next 24 hours.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux, as measured by the GOES-18 satellite, reached but did not exceed the 1000 pfu threshold in the past 24 hours. For the next 24 hours it is expected to repeat the same pattern. The 24h electron fluence remain at normal levels during the past 24 hours and is expected to remain at normal levels for the next 24 hours.
