PLAIN
NOTE: the above forecasts are valid from 1230UT, 25 Feb 2018 until 27 Feb
2018
PREDICTIONS FOR 25 Feb 2018 10CM FLUX: 068 / AP: 009
PREDICTIONS FOR 26 Feb 2018 10CM FLUX: 068 / AP: 018
PREDICTIONS FOR 27 Feb 2018 10CM FLUX: 068 / AP: 007
COMMENT: There are no sunspot regions on the visible hemisphere of the
Sun
and flaring level is very low. The chance for a C flare in the next 24
hours is estimated at 5%.
No Earth-directed Coronal Mass Ejections (CMEs) were observed in available
coronagraphic imagery.
The greater than 10 MeV proton flux was at nominal levels in the past 24
hours, and is expected to stay at nominal levels in the next 24 hours.
The solar wind speed (recorded by DSCOVR) further decreased from about
475
to 415 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF)
was directed mainly toward the Sun and its magnitude ranged between about
5
and 8 nT. Bz was never below -5 nT. On February 25, the solar wind is
expected to be at nominal levels, with a chance for occasional periods
of
slightly enhanced solar wind. On February 26, an enhancement in the solar
wind is expected, associated with a high speed stream from the negative
polarity south polar coronal hole. A return to nominal solar wind values
is
expected on February 27.
Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between
0
and 2) were registered in the past 24 hours. Quiet to unsettled geomagnetic
levels (K Dourbes < 4) are expected for February 25 and 27, with a chance
for active intervals (K Dourbes = 4). Active levels (K Dourbes = 4) are
possible on February 26, with a chance for minor storm intervals (K Dourbes
= 5).
TODAY'S ESTIMATED ISN : 000, BASED ON 22 STATIONS.
