2017
PREDICTIONS FOR 26 Nov 2017 10CM FLUX: 075 / AP: 006
PREDICTIONS FOR 27 Nov 2017 10CM FLUX: 075 / AP: 008
PREDICTIONS FOR 28 Nov 2017 10CM FLUX: 075 / AP: 016
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. A small filament eruption occurred near disk centre
at around 04:00 UT on 2017-Nov-25, Coronagraph imagery suggests the bulk
of
the ejection headed to the East of the Sun-Earth line and only a glancing
blow, if any, can be expected. If so, this is anticipated to arrive at
Earth late on 2017-Nov-28. However, projection effects make it difficult
to
ascertain an accurate speed. 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 a low probability of C-class flares.
The solar wind speed been been decreasing from 400 to 320 km/s over the
past 24 hours. The total magnetic field strength has fluctuated between
0
and 5 nT, peaking around 00:00 UT this morning. The Bz component has
fluctuated between positive and negative, between -4 and +5 nT. Geomagnetic
conditions ranged between Kp index 0-2 (NOAA) and local K index 0-2
(Dourbes) over the past 24 hours. A small transient coronal hole has just
passed the central meridian and may enhance solar wind speeds in a couple
of days. Geomagnetic conditions are expected to be quiet.
TODAY'S ESTIMATED ISN : 018, BASED ON 17 STATIONS.
