Sluneční záblesky : Quiet conditions (<50% probability of C-class flares)
Geomagnetická situace : Quiet (A<20 and K<4)
Sluneční protony : Quiet
Komentář : The solar activity has been quiet over the past 24 hours with
X-ray flux remaining below C level. Catania sunspot group 86 (NOAA active
region 2713) remained stable. A new relatively small sunspot (Catania
sunspot group 87, NOAA active region 2714) has emerged yesterday. Quiet
flaring conditions are expected for the next 24-hour period.
No Earth directed Coronal Mass Ejection has been observed. The greater than
10 MeV solar protons flux remained at nominal levels over the past 24 hours
and is expected to remain so.
The Earth is currently under the influence of the solar wind associated
with the positive polarity coronal hole in the northern hemisphere that has
passed the central meridian on Jun 15. The wind speed values fluctuated
between 480 to 530 km/s, and is expected to start to decrease within the
next 24-hour. The total magnetic field strength has slowly decreased from
around 10 nT to its nominal values below 5 nT, while Bz component
fluctuated between -5 and +5 nT. The enhanced solar wind conditions are
expected to persist until while under the influence of the wind associated
with the coronal hole.
The geomagnetic conditions have been unsettled over the past 24 hours due
to the arrival of the solar wind associated with the coronal hole. Due to
the ongoing enhancement of the solar wind, active geomagnetic conditions
may be expected until the Earth is entering the slow solar wind speed
regime.
