PREDICTIONS FOR 15 Nov 2017 10CM FLUX: 074 / AP: 013
PREDICTIONS FOR 16 Nov 2017 10CM FLUX: 075 / AP: 011
PREDICTIONS FOR 17 Nov 2017 10CM FLUX: 076 / AP: 006
COMMENT: There were no C-class and even no B-class flares reported during
last 24 hours. The only active region presently observed on the visible
side of the solar disc is Catania sunspot group 63 (NOAA AR 2687) which
has
beta configuration of its photospheric magnetic field and might be source
of the B-class and isolated C-class flares (probability of only about 7%)
in the coming hours. No Earth directed CMEs were observed in the last 24
hours, and the solar protons remained at background level.
The solar wind speed is presently about 400 km/s and the interplanetary
magnetic field magnitude is about 8 nT.
Due to longer intervals of the negative value of the Bz component,
unsettled to active geomagnetic conditions were reported in the late
evening of November 14 (local station at Dourbes reported interval with
Kand NOAA reported interval of Kp=3).
The fast flow associated with the low latitude extension of the northern
polar coronal hole (reached central meridian in the early morning of
November 11) is expected to arrive at the Earth today. The arrival of the
fast solar wind migh induce disturbed geomagnetic conditions (up to Kp=4).
The geomagnetic conditions are presently quiet to unsettled, and we expect
unsettled to active conditions later today or early morning tomorrow.
TODAY'S ESTIMATED ISN : 014, BASED ON 12 STATIONS.
