PLAIN
NOTE: the above forecasts are valid from 1230UT, 25 Nov 2017 until 27 Nov
2017
PREDICTIONS FOR 25 Nov 2017 10CM FLUX: 075 / AP: 011
PREDICTIONS FOR 26 Nov 2017 10CM FLUX: 074 / AP: 008
PREDICTIONS FOR 27 Nov 2017 10CM FLUX: 074 / AP: 008
COMMENT: Over the past 24 hours solar activity has been quiet. No
significant flares have been recorded. All Active Regions (AR) have shown
low levels of activity. No Earth directed Coronal Mass Ejections (CMEs)
have been detected. The greater than 10 MeV proton flux remained at
background levels over the past 24 hours. Solar activity is expected to
remain low over the next 24 hours with a low probability of C-class flares.
The solar wind speed fluctuated between 350 and 450 km/s over the past
24
hours, peaking around 00:00 UT this morning. The total magnetic field
strength has fluctuated between 3 and 10 nT, peaking around 00:00 UT this
morning. The Bz component has fluctuated between -6 and +8 nT. Geomagnetic
conditions ranged between Kp index 0-4 (NOAA) and local K index 0-5
(Dourbes) over the past 24 hours. The enhanced solar wind speed and
negative Bz this morning resulted in a peak in geo-magnetic conditions
(K=5). A small transient coronal hole has just passed the central meridian
and will enhance solar wind speeds in a couple of days. Geomagnetic
conditions are expected to be quiet to unsettled.
TODAY'S ESTIMATED ISN : 016, BASED ON 11 STATIONS.
