Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was at low levels over the last 24 hours with few low C-class flares. The largest flare was a C4.2-class flare produced by the NOAA Active Region AR-3354, which is currently the most complex region on the disc (Beta-gamma-delta). We expect the activity remaining mostly at low levels with several C-class flares, and possible isolated M-class flare in the next 24 hours.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CME) were observed in the SOHO/LASCO coronograph images over the past 24 hours.

Dziury koronalne

A small equatorial coronal hole (negative polarity) has transited the central meridian today.

Wiatr słoneczny

The solar wind parameters showed a return to slow solar wind regime. The wind speed decreased form 550 km/s to 430km/h. The total interplanetary magnetic field (Bt) also decreased to values below 7 nT. The southward component (Bz) was fluctuating between -3.8 nT and 6.3 nT being manly positive. The interplanetary magnetic field phi angle was positive, directed outward the Sun.

Geomagnetyzm

Geomagnetic conditions were quiet to unsettled (NOAA Kp<4 and K_BEL<4). Geomagnetic activity is expected to remained quiet to unsettled.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was at background levels over the past 24 hours and is expected to remain so for the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

Electron fluxes at GEO: The greater than 2 MeV electron flux was above the 1000 pfu threshold for a short period. It is expected to remain close to the threshold for the next 24 hours. The 24-hour electron fluence was at normal to moderate levels for the past 24 hours and it is expected to remain at these levels for the next 24 hours.
