Mezinárodní číslo slunečních skvrn :
013
Sluneční záblesky : Quiet conditions (<50% probability of C-class flares)
Geomagnetická situace : Active conditions expected (A>=20 or K=4)
Sluneční protony : Quiet
Komentář : The solar activity has been quiet over the past 24 hours. A
relatively small bipolar sunspot emerged on the solar disc (Catania sunspot
group 21), but does not show any strong activity so far. The X-ray flux
remained below B-level. Solar activity is expected to remain at low levels
for the next 24 hours.
No Earth directed coronal mass ejections (CME) were observed over the last
24 hours in the available coronagraph imagery. The greater than 10 MeV
proton flux remained at background levels over the past 24 hours and is
expected to remain at low levels.
The solar wind speed varied between 315 km/s and 420 km/s (ACE). The
magnetic field showed some enhancement with Bz that varied between -8 nT
and +9 nT and the total interplanetary magnetic field between 2 nT and 10
nT. The solar wind parameters might remain slightly enhanced for the coming
days due to the possible effect of the South pole coronal hole wind
streams.
Quiet to unsettle geomagnetic conditions were observed with short period of
active conditions, with the Kp index (NOAA) ranging between 1-3 and the
local K index (Dourbes) ranging between 1-4 over the past 24 hours.
