PLAIN
NOTE: the above forecasts are valid from 1230UT, 19 Feb 2018 until 21 Feb
2018
PREDICTIONS FOR 19 Feb 2018 10CM FLUX: 069 / AP: 019
PREDICTIONS FOR 20 Feb 2018 10CM FLUX: 069 / AP: 024
PREDICTIONS FOR 21 Feb 2018 10CM FLUX: 069 / AP: 012
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.
Solar wind speed measured by DSCOVR was between about 520 and 670 km/s
in
the past 24 hours, with current values around 570 km/s. The Interplanetary
Magnetic Field (IMF) was directed towards the Sun and its magnitude varied
between about 2 and 8 nT. Bz was never below -5.5 nT. This enhanced solar
wind is indicative of a negative coronal hole high speed stream. Quiet
to
active geomagnetic conditions (K Dourbes between 2 and 4; NOAA Kp between
2
and 5) were registered in the past 24 hours. Quiet to active levels (K
Dourbes < 5) are possible on February 19, 20 and 21 due to the influence
of
the high speed stream associated with a negative coronal hole, with a
chance for minor storm conditions (K Dourbes = 5).
TODAY'S ESTIMATED ISN : 000, BASED ON 08 STATIONS.
