Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was at moderated levels over the last 24 hours with several low C-class flares and one M-class flare. The M3.8-class flares produced at 14:14 UTC on Jun 29 by the NOAA Active Region AR-3354, which is now the most complex region on the disc (Beta-gamma-delta). The other complex active regions have also produced several C-class flares. We expect the activity remaining mostly at low to moderated 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.

Wiatr słoneczny

The solar wind parameters showed mild enhancement due to the arrival of the high-speed streams associated to the coronal hole (negative polarity) that crossed the solar meridian on Jun 24.The wind speed ranged between 450 km/s to 550 km/h. The total interplanetary magnetic field (Bt) slightly increased up to the 8.1 nT. The southward component (Bz) was fluctuating between -5.4 nT and 4.2 nT. The interplanetary magnetic field phi angle was negative, directed toward the Sun, then around 01:00 UTC it rotated to the positive sector. Mild enhancement of the solar wind conditions are expected for the following day.

Geomagnetyzm

Geomagnetic conditions were unsettled to active (NOAA Kp=4 and K_BE=4) due to the arrival of the high-speed streams associated to the coronal hole (negative polarity) that crossed the solar meridian on Jun 24, and the negative value of the southward component (Bz) of the interplanetary magnetic field. Geomagnetic activity is expected to remain 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.

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.
