Aktuální sluneční data:
04.červen 2020 - 12:31 UT(GMT)
Mezinárodní číslo slunečních skvrn :
Sluneční záblesky : Quiet conditions (<50% probability of C-class flares)
Geomagnetická situace : Quiet (A<20 and K<4)
Sluneční protony : Quiet
Komentář : Solar X-ray flux remained below C level throughout the period.
The region in the South that rotated onto the visible disc was numbered as
NOAA region 2765, but appears fairly inactive with a unipolar spot.
The overall probability for C flaring is low.
A filament eruption from around S50W20 is visible in SDO/AIA 304 images
starting around 23:00UT. Coronagraph data, however, do not show any clear
related CME signatures.
There were no Earth directed Coronal Mass Ejections (CMEs) observed in
The greater than 10 MeV proton flux levels were at background values and
are expected to continue to be at background level.
The greater than 2 MeV electron flux has been nominal over the past days.
Solar wind conditions were nominal with Solar wind speed decreasing from
around 340 to around 310 km/s. The total magnetic field was below 5nT with
an insignificant Bz component. The magnetic field phi angle was in the
negative sector most of the time but switched into the positive sector
Solar wind conditions are expected to be near nominal over the next 24-48
hours, but are likely to become enhanced on June 6 under influence a low
latitude extension of the northern polar coronal hole.
Geomagnetic conditions were quiet (both NOAA Kp and local K Dourbes 0-2).
Quiet to unsettled geomagnetic conditions are expected over the next days,
later from June 6 increasing to unsettled to active conditions.
