INFO FROM SIDC - RWC BELGIUM 2017 Sep 24 12:30UTC

Over the past 24 hours the solar activity was very low. Only small B-class
flares and one non-Earth directed slow-speed CME were recorded. Catania
sunspot groups 56 (NOAA active regions 2681) has increased its magnetic
complexity (from Alpha to Beta class), but has not shown any flaring
activity. The returning region NOAA active region 2682 (previously, Catania
sunspot group 46, NOAA active region 2673) is now on the visible disc and
is the source of the slow-speed CME and B-class flaring activity. Its
magnetic complexity is difficult to estimate due to the projection effect,
however, it seems to have drastically decay from the previous solar
rotation. We expect the solar activity to increase due to the return of
this region with C-class flares. 

No Earth directed CMEs have been observed and the solar protons remained at
background level over the past 24 hours.
The Earth remained inside a slow solar wind flow. The speed has further
decreased from about 400 to 330 Km/s. The interplanetary magnetic field
magnitude remained below 6 nT and the Bz component fluctuated between -5
and 5 nT. The associated fast solar wind to the small equatorial coronal
hole that has crossed the central meridian on Sept 20 has not arrived yet
and is expected to arrive at Earth today. A new larger coronal hole with
positive polarity is currently facing Earth. This coronal hole is elongated
from the north solar pole to the solar Equator and its high speed stream is
expected to arrive at Earth in about 3 days from now (on Sept 27).

Geomagnetic conditions were quiet with Kp (NOAA) and local K (Dourbes)
indexes ranging between 1-2. The geomagnetic conditions are expected to
become more active with the arrival of the high speed stream from the
coronal hole that has crossed the central meridian on Sept 20. As this
coronal hole was relatively small, no strong or sever magnetic storm is
expected.
