PLAIN
NOTE: the above forecasts are valid from 1230UT, 22 Feb 2018 until 24 Feb
2018
PREDICTIONS FOR 22 Feb 2018 10CM FLUX: 068 / AP: 012
PREDICTIONS FOR 23 Feb 2018 10CM FLUX: 068 / AP: 012
PREDICTIONS FOR 24 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) varied between about 380 and
430
km/s in the past 24 hours, with current values around 405 km/s. The
Interplanetary Magnetic Field (IMF) was directed mainly toward the Sun
and
its magnitude ranged between about 1 and 10 nT. Bz had excursions below
-5
nT between 07:40 and 09:30 UT on February 22. On February 22, 23 and 24
the
solar wind is expected to be at nominal levels, possibly with occasional
periods of enhanced solar wind as the Earth comes close to the high speed
stream associated with the negative polarity south polar coronal hole.
Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between
1
and 2) were registered in the past 24 hours. Quiet to unsettled geomagnetic
levels (K Dourbes < 4) are expected on February 22, 23 and 24, with a
chance for active intervals (K Dourbes = 4) when the Earth comes close
to
the high speed stream associated with the negative polarity south polar
coronal hole.
TODAY'S ESTIMATED ISN : 000, BASED ON 22 STATIONS.
