NOTE: the above forecasts are valid from 1230UT, 09 Nov 2017 until 11 Nov
2017
PREDICTIONS FOR 09 Nov 2017 10CM FLUX: 068 / AP: 022
PREDICTIONS FOR 10 Nov 2017 10CM FLUX: 068 / AP: 019
PREDICTIONS FOR 11 Nov 2017 10CM FLUX: 068 / AP: 006
COMMENT: The solar activity is quiet as the solar disc remains spotless;
no
flares and no active regions have been recorded in past 24 h on the disc.
The X-ray flux is expected to remain below C level.
No Earth directed Coronal Mass Ejections have been observed and the solar
protons flux remained at background levels over the past 24 hours.
The Earth remained in the fast solar wind with a speed of about 600-650
km/s. On Nov 09 early morning the solar wind started to decrease slowly
to
reached the speed of 550 km/s. The interplanetary magnetic field magnitude
has also slowly decreased from 7 nT to below 5 nT. The Bz component was
fluctuating between -7 and 7 nT being mainly negative and is currently
around -5 nT. The solar wind speed is expected to continue to decrease
until it reaches its nominal level by tomorrow.
Due to the fast solar wind and the Bz component of the interplanetary
magnetic field being manly southward, unsettle to disturb geomagnetic
conditions were observed with local K Dourbes 2-5 and NOAA Kp 3-5. The
geomagnetic conditions are expected to remain disturb as long as the Earth
remains in the solar wind flow associated with the high speed stream coming
from the coronal hole (that has crossed the central meridian on Nov 4).
Minor geomagnetic storms cannot be excluded, especially if Bz component
remains negative for long period of time.
TODAY'S ESTIMATED ISN : 000, BASED ON 16 STATIONS.
