2017
PREDICTIONS FOR 20 Sep 2017 10CM FLUX: 073 / AP: 007
PREDICTIONS FOR 21 Sep 2017 10CM FLUX: 076 / AP: 007

COMMENT: Over the past 24 hours the solar activity was very low, only few
B-class flares have been recorded. Catania sunspot group 55 (NOAA active
region 2680) is unlikely to produce any flaring activity. The returning
region (Catania sunspot group 49 / NOAA active region 2676) is currently
on
the East solar limb and is the source region of the B-class flares. We
expect the solar activity to increase with B-class flares and a small
probability of C-class flare coming from this returning region.
No Earth directed CMEs have been observed and the solar protons remained
at
background level in the past 24 hours.
The Earth is currently inside a slow (around 500 km/s) solar wind flow.
The
interplanetary magnetic field magnitude remained below 5 nT and the Bz
component fluctuating between -4 and 4 nT. The solar wind is expected
maintain its nominal conditions over the next days.
Geomagnetic conditions were quiet to unsettled (local K Dourbes 1-3, NOAA
Kp 2-3) and are expected to remain quiet over the next days.
TODAY'S ESTIMATED ISN : 017, BASED ON 20 STATIONS.
