PLAIN
NOTE: the above forecasts are valid from 1230UT, 02 Oct 2017 until 04 Oct
2017
PREDICTIONS FOR 02 Oct 2017 10CM FLUX: 085 / AP: 007
PREDICTIONS FOR 03 Oct 2017 10CM FLUX: 084 / AP: 007
PREDICTIONS FOR 04 Oct 2017 10CM FLUX: 083 / AP: 005
COMMENT: Solar activity was at very low levels. The 3 visible sunspot
groups were quiet. 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.
Some coronal dimming was observed at S10W50 on 01 October between 14 and
17UT, followed by post-eruption coronal loops over and to the northwest
of
NOAA 2682. The x-ray flux seems to have been mildly enhanced in response
to
this eruptive event. Some coronal mass ejections (CMEs) were observed by
SOHO/LASCO starting late on 01 October, but they were relatively slow
(CACTus) and directed to the west (no obvious earth-directed component).
Solar wind speed varied between 430 and 500 km/s (DSCOVR), ending the
period near 440 km/s. Bz varied between -5 and +2 nT (DSCOVR). The
interplanetary magnetic field was mostly directed away from the Sun. A
small negative equatorial coronal hole (CH) started transiting the central
meridian on 01 October.
The geomagnetic field was at quiet to unsettled levels, with Kp featuring
a
single active episode during the 03-06UT interval. Quiet to unsettled
geomagnetic conditions are expected, with an active episode still possible.
The arrival of the particle stream associated with the aforementioned CH
is
expected for 04 or 05 October, with increasing chances on active
geomagnetic conditions.
TODAY'S ESTIMATED ISN : 034, BASED ON 21 STATIONS.
