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 : Over the past 24 hours solar activity has been very low. The
visible solar disc was spotless and no significant flares have been
recorded. No Earth directed Coronal Mass Ejections (CMEs) have been
detected in the available coronagraph imagery. The greater than 10MeV
proton flux remained at background levels over the past 24 hours. Solar
activity is expected to remain very low over the next 24 hours.
The solar wind was at background levels over the last 24 hours, with a
minimum and maximum speed recorded of around 295 km/s and 355 km/s,
respectively. The total magnetic field strength fluctuated between 0.4 and
5.7 nT. The Bz component ranged between approximately -3 and +4 nT. The phi
angle was predominantly negative, switching to the positive sector at
around 4 UT.
Geomagnetic conditions have been quiet to unsettled over the past 24 hours,
with Kp index (NOAA) and local K index (Dourbes) ranging between 0-2 and
0-3, respectively. Quiet geomagnetic conditions are expected over the next
24 hours, with the possibility of isolated unsettled intervals.
