PLAIN
NOTE: the above forecasts are valid from 1230UT, 03 Oct 2017 until 05 Oct
2017
PREDICTIONS FOR 03 Oct 2017 10CM FLUX: 085 / AP: 010
PREDICTIONS FOR 04 Oct 2017 10CM FLUX: 085 / AP: 010
PREDICTIONS FOR 05 Oct 2017 10CM FLUX: 084 / AP: 015
COMMENT: Solar activity was at very low levels. The 2 visible sunspot
groups were quiet. No earth-directed coronal mass ejections (CMEs) were
observed in available coronagraphic imagery. The greater than 10 MeV proton
flux was at nominal levels.
Quiet flaring conditions are expected, with a small chance on a C-class
flare.
Solar wind speed varied between 390 and 440 km/s (DSCOVR), ending the
period near 410 km/s. Bz fluctuated between -6 and +5 nT. The
interplanetary magnetic field was mostly directed away from the Sun, with
"towards" excursions from 02UT onwards. A small negative equatorial coronal
hole (CH) transited the central meridian on 01-03 October.
The geomagnetic field was at quiet to unsettled levels, and is expected
to
remain so. The particle stream associated with the aforementioned CH may
start influencing the earth environment on 04 or 05 October, increasing
the
likelihood on an active geomagnetic episode.
TODAY'S ESTIMATED ISN : 027, BASED ON 16 STATIONS.
