PLAIN
NOTE: the above forecasts are valid from 1230UT, 24 Feb 2018 until 26 Feb
2018
PREDICTIONS FOR 24 Feb 2018 10CM FLUX: 068 / AP: 014
PREDICTIONS FOR 25 Feb 2018 10CM FLUX: 068 / AP: 012
PREDICTIONS FOR 26 Feb 2018 10CM FLUX: 068 / AP: 010
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) gradually decreased from about
550 to 470 km/s in the past 24 hours. The Interplanetary Magnetic Field
(IMF) was directed mainly toward the Sun and its magnitude ranged between
about 0 and 9 nT. Bz was often below -5 nT between 22:40 UT on February
23
and 00:20 UT on February 24, and between 01:30 UT and 02:50 UT. On February
24, 25 and 26 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 to active geomagnetic conditions (K Dourbes between 1 and 4; NOAA
Kp
between 2 and 3) were registered in the past 24 hours. Quiet to unsettled
geomagnetic levels (K Dourbes < 4) are expected for February 24, 25 and
26,
with a chance for active intervals (K Dourbes = 4).
TODAY'S ESTIMATED ISN : 000, BASED ON 23 STATIONS.
