Päikese aktiivsus
24 h summaarne
Solar activity reached moderate levels (R1/Minor). Region 3932 (S17E42,
Ekc/beta-gamma) produced an impulsive M1.1 flare at 22/2049 UTC;
the largest event of the period. Development continued among the
cluster of active regions in the SE quadrant. No Earth-directed CMEs
were detected in available data.
Ennustus
M-class flare activity is likely (R1/R2-Minor/Moderate), with a slight
chance for an isolated X-class flare (R3/Strong), over 23-25 Dec.
Energeetilised osakesed
24 h summaarne
The greater than 10 MeV proton flux remained elevated above background
but well below the S1 threshold, mostly due to activity that erupted on
the far side of the Sun over 20 Dec. The greater than 2 MeV electron
flux was at normal and moderate levels.
Ennustus
There remains a slight chance for the greater than 10 MeV proton flux to
reach S1 (Minor) levels over 23-25 Dec. The greater than 2 MeV electron
flux is expected to continue at normal to moderate levels through 25
Dec.
Päikese tuul
24 h summaarne
Solar wind parameters were enhanced this period. Total field reached a
peak of 9 nT and Bz varied between +8/-7 nT. Solar wind speeds ranged
between ~500-700 km/s through most of the period. Phi angle was
negative.
Ennustus
Enhanced solar wind conditions are expected to prevail over 23-25 Dec.
Negative polarity CH HSS influences are expected over 23-25 Dec and
there is a chance to see the glancing influences of a CME (from 20 Dec)
on 24 Dec.
Georuum
24 h summaarne
The geomagnetic field ranged from quiet to unsettled levels.
Ennustus
The geomagnetic field is expected to be quiet to unsettled, with a
chance for isolated active periods, over 23-25 Dec due to negative
polarity CH HSS influences. An additional enhancement is possible on 24
Dec from the glancing influences of a CME that left the Sun on 20 Dec.
