NOTE: the above forecasts are valid from 1230UT, 19 Sep 2017 until 21 Sep
2017
PREDICTIONS FOR 19 Sep 2017 10CM FLUX: 072 / AP: 005
PREDICTIONS FOR 20 Sep 2017 10CM FLUX: 073 / AP: 006
PREDICTIONS FOR 21 Sep 2017 10CM FLUX: 076 / AP: 006
COMMENT: Over the past 24 hours the solar activity was very low with no
flaring activity recorded. The Catania sunspot group 55 (NOAA active region
2680) is the only present region on the disc, and is unlikely to produce
any flaring activity. We expect the solar activity to remain quiet until
the returning region (Catania sunspot group 49 / NOAA active region 2676)
will come from behind the East solar limb by the end of the day.
No Earth directed CMEs have been observed and the solar protons remained
at
background level in the past 24 hours.
Solar wind speed starts a slow overall decline from about 700 km/s to 500
km/s. The interplanetary magnetic field magnitude returned to its nominal
3-6 nT range with the Bz component fluctuating between -4 and 4 nT. The
solar wind is expected to further recover to nominal conditions over the
next days.
Geomagnetic conditions were quiet to active (local K Dourbes 1-4, NOAA
Kp
1-3) and are expected to remain quiet to unsettled over the next days.
TODAY'S ESTIMATED ISN : 012, BASED ON 21 STATIONS.
