NOTE: the above forecasts are valid from 1230UT, 17 Nov 2017 until 19 Nov
2017
PREDICTIONS FOR 17 Nov 2017 10CM FLUX: 075 / AP: 012
PREDICTIONS FOR 18 Nov 2017 10CM FLUX: 076 / AP: 010
PREDICTIONS FOR 19 Nov 2017 10CM FLUX: 076 / AP: 012
COMMENT: Solar flaring activity is low, with only few low B-class flares
reported. All reported flares originated from the Catania sunspot group
63
(NOAA AR 2687) which maintains the beta configuration of its photospheric
magnetic field. We do not expect significant change of flaring activity
in
the coming hours. During last 24 hours there were no Earth directed CMEs
reported, and the solar protons remained at background level.
The solar wind speed presently amounts about 430 km/s (its maximum value
within the last 24 hours was about 510 km/s). The interplanetary magnetic
field magnitude is stable having the value of about 4 nT.
The fast solar wind associated with the equatorial coronal hole which
reached central meridian in the early morning of November 16 is expected
to
arrive at the Earth on November 19.
The fast flow associated with the low latitude extension of the southern
polar coronal hole (reached central meridian in the late evening of
November 13) is expected to arrive at the Earth this evening.
The geomagnetic conditions are presently quiet to unsettled, we expect
unsettled to active geomagnetic conditions later today due to the arrival
of the fast solar wind.
TODAY'S ESTIMATED ISN : 024, BASED ON 22 STATIONS.
