Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low during the past 24 hours. NOAA Active Region (AR) 3865 (magnetic configuration Beta- Gamma, Catania sunspot group 10) produced almost all the activity. The same AR also emitted the brightest flares, two C4 yesterday at 19:38 and 20:16 UTC. Nevertheless NOAA AR 3685 and 3670 (magnetic configuration Beta-Gamma, Catania sunspot group 6) have increased in magnetic complexity and are both likely to produced M-class flares in the next 24 hours. There is also a chance of X-class flaring, especially from NOAA AR 3685 during the next 24 hours.

Koronalny wyrzut masy

No Earth directed Coronal Mass Ejections (CMEs) have been observed in the available coronagraph data.

Wiatr słoneczny

Solar Wind (SW) conditions were typical of the slow SW regime during the past 24 hours. The SW speed gradually dropped from 450 to 360 km/s, while the total interplanetary magnetic field (Bt) ranged between 4 and 9 nT. The North-South magnetic component (Bz) fluctuated between -8 and 3 nT and the interplanetary magnetic field phi angle was predominantly directed away from the Sun in the last 24 hours. The SW conditions are expected to remain in the same pattern for the next 24 hours.

Geomagnetyzm

The global geomagnetic conditions were both globally and locally at unsettled to low levels (NOAA Kp 1+ to 3- and K BEL 2 to 3) during he past 24 hours. They are expected to be predominantly quiet, both globally and locally, during the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux, as measured by the GOES-18 satellite, was in low levels during the past 24 hours. It is likely that it will remain at low levels in the next 24 hours, however, there is a small chance of a new proton event and an increase in flux above the 10 pfu alert level.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-18 satellite, was at low levels during the last 24 hours and is expected to remain at those levels for the next 24 hours. The 24h electron fluence was at normal levels during the past 24 hours and is expected to remain to those levels in the next 24 hours.
