NOTE: the above forecasts are valid from 1230UT, 14 Nov 2017 until 16 Nov
2017
PREDICTIONS FOR 14 Nov 2017 10CM FLUX: 073 / AP: 011
PREDICTIONS FOR 15 Nov 2017 10CM FLUX: 074 / AP: 015
PREDICTIONS FOR 16 Nov 2017 10CM FLUX: 075 / AP: 006
COMMENT: Solar activity remains to be low. The background X-ray flux has
increased to a low B-level, due to appearance of the active region which
rotated from the behind of the East solar limb. This, still not numbered
active region, might be the source of B-class and possibly, but not very
probably, also low C-class flares in the coming hours.
During last 24 hours no Earth directed CMEs have been observed and the
solar protons remained at background level.
The solar wind speed is presently 380 km/s, and the interplanetary magnetic
field magnitude is about 9 nT.
The in situ observations (from DSCOVR satellite), showed sudden increase
of
the interplanetary magnetic field magnitude, density, temperature and the
solar wind speed at about 00:48 UT this morning, indicating arrival of
a
shock wave. The shock is probably associated with the large filament
eruption from the north-east quadrant of the Sun, which took place in the
morning of November 10.
The geomagnetic conditions are quiet to unsettled and we expect them to
stay so in the coming hours with the possibility of the active geomagnetic
conditions starting from this evening, due to expected arrival of the fast
solar wind associated with with the low latitude extend of the northern
polar coronal hole (reached central meridian in the early morning of
November 11).
TODAY'S ESTIMATED ISN : 014, BASED ON 15 STATIONS.
