2017
PREDICTIONS FOR 29 Sep 2017 10CM FLUX: 093 / AP: 015
PREDICTIONS FOR 30 Sep 2017 10CM FLUX: 093 / AP: 012

COMMENT: Over the past 24 hours solar activity has been low. No significant
flares have been recorded. Catania group 55 (NOAA AR region 2681) has been
most active, producing one B2.9 flare peaking at 14:34 UT yesterday
(29-Sep-2017). No Earth directed Coronal Mass Ejections (CMEs) have been
detected in coronograph observations. The greater than 10MeV proton flux
remained at background levels over the past 24 hours. Solar activity is
expected to remain low over the next 24 hours with some probability of
C-class flares.
The Earth is still inside the fast solar wind stream with the speed of
about 640 km/s. However the magnitude of the interplanetary magnetic field
remained below 5 nT over the past 24 hours, while Bz component varied
between -4 and 4.4 nT. Geomagnetic conditions were active yesterday
afternoon (Kp = 4 at 12-21 UT; 28 Sep-2017). Later, after a single episode
of minor storm (Kp = 5 at 21-24 UT; 28-Sep-2017) geomagnetic conditions
became unsettled (29-Sep-2017) with Kp (NOAA) and local K (Dourbes) indexes
ranging between 1-3 and 2-3 respectively. The geomagnetic conditions are
expected to remain from unsettled to active (Kp = 4) at least until
01-Oct-2017.
TODAY'S ESTIMATED ISN : 046, BASED ON 20 STATIONS.
