NOTE: the above forecasts are valid from 1230UT, 10 Sep 2017 until 12 Sep
2017
PREDICTIONS FOR 10 Sep 2017 10CM FLUX: 100 / AP: 006
PREDICTIONS FOR 11 Sep 2017 10CM FLUX: 095 / AP: 007
PREDICTIONS FOR 12 Sep 2017 10CM FLUX: 092 / AP: 007
COMMENT: Catania group 46 (NOAA active region 2673) continued to dominate
solar activity. The largest flare was an M1.1 flare peaking at 13:53UT
September 9.
This region has currently reached the Western limb. Other regions on disk
were stable or in decay while a new region has appeared from over the
Eastern limb.
As long as Catania group 46 has not fully disappeared over the Western
limb, further M flares must be accounted for, with also a chance for an
X
flare remaining.
Associated to the M1.1 flare a CME was seen in coronagraph images. It is
directed Westward and appears to be limited in angular extent and hence
will not be influencing Earth.
The >10MeV proton flux has dropped below 1pfu during the period and is
further approaching background values.
Associated with the activity in Catania sunspot group 46 (NOAA region
2673), chances for renewed increases in proton fluxes remain, but are
decreasing.
A positive polarity coronal hole in the northern hemisphere is starting
to
transit the central meridian and could influence solar wind conditions
from
September 13 onwards.
Solar wind conditions have been stable with solar wind speed around
550km/s, total magnetic field nominal at 4-5nT and Bz mostly positive.
The slightly elevated solar wind speed is expected to persist over the
next
24 hours and later decline towards nominal values.
Geomagnetic conditions were quiet (local K Dourbes 0-2, NOAA Kp 0-1).
Over the next days, quiet to unsettled geomagnetic conditions are expected.
TODAY'S ESTIMATED ISN : 047, BASED ON 17 STATIONS.
