NOTE: the above forecasts are valid from 1230UT, 17 Feb 2018 until 19 Feb
2018
PREDICTIONS FOR 17 Feb 2018 10CM FLUX: 072 / AP: 019
PREDICTIONS FOR 18 Feb 2018 10CM FLUX: 071 / AP: 010
PREDICTIONS FOR 19 Feb 2018 10CM FLUX: 070 / AP: 007
COMMENT: Over the past 24 hours solar activity has been low. No significant
flares have been recorded. Active Region (AR) 2699 (Mcintosh class:Hax;
Mag. type:Alpha) has reached the west limb. The greater than 10MeV proton
flux remained at background levels over the past 24 hours. No Earth
directed Coronal Mass Ejections (CMEs) have been detected. Over the next
24
hours there is a small chance of C-class flares.
The solar wind speed has increased from around 350 to 500 km/s over the
past 24 hours. The total magnetic field strength has slowly decreased from
around 10 to 5 nT, the Bz component has fluctuated between -6 and +6 nT.
Geomagnetic conditions ranged between Kp index 1-4 (NOAA) and local K index
1-3 (Dourbes) over the past 24 hours. A High Speed Stream (HSS) associated
with a large coronal hole that passed the central meridian a couple of
days
ago has enhanced solar wind speeds at Earth. Geomagnetic conditions are
expected to be quiet to unsettled.
TODAY'S ESTIMATED ISN : 000, BASED ON 15 STATIONS.
