Mezinárodní číslo slunečních skvrn :
000
Sluneční záblesky : Quiet conditions (<50% probability of C-class flares)
Geomagnetická situace : Quiet (A<20 and K<4)
Sluneční protony : Quiet
Komentář : Solar activity was at very low levels. The Sun remains spotless
and no flares have been observed. 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. Solar activity is expected to remain at very low
levels.
The solar wind speed gradually increased over the period from 370 to a
maximum of around 500 km/s at 07:15 UT (ACE). The Bz varied between -5 and
+4 nT. The interplanetary magnetic field was predominantly directed away
from the Sun (positive sector). Quiet to unsettled geomagnetic conditions
were observed, with the Kp index (NOAA) ranging between 0-2 and the local K
index (Dourbes) ranging between 1-3 over the past 24 hours.
Quiet geomagnetic conditions are expected with possible isolated unsettled
intervals.
