NOTE: the above forecasts are valid from 1230UT, 07 Feb 2018 until 09 Feb
2018
PREDICTIONS FOR 07 Feb 2018 10CM FLUX: 077 / AP: 003
PREDICTIONS FOR 08 Feb 2018 10CM FLUX: 078 / AP: 010
PREDICTIONS FOR 09 Feb 2018 10CM FLUX: 079 / AP: 006
COMMENT: Solar activity was low. NOAA AR 2699 produced many B-class flares
and one C1.0 flare that peaked at 18:58 UT yesterday. Now NOAA 2699 has
beta magnetic field configuration and is expected to produce more B-class
flares and, with some chance, C-class flares. Proton flux levels are at
background values and are expected to remain so. No Earth-directed CMEs
were observed.
Solar wind parameters were still under the influence of a low latitude
extension of the northern polar coronal hole. Solar wind speed was between
400-460 km/s with interplanetary magnetic field magnitude ranged from 2
to
6 nT. Geomagnetic conditions have been mostly quiet reaching unsettled
levels (K = 3) overnight, as measured locally at Dourbes. Geomagnetic
conditions are expected to remain quiet today. Isolated episodes of
unsettled levels are possible from tomorrow due to the better connection
to
a low latitude extension of the northern polar coronal hole.
TODAY'S ESTIMATED ISN : 022, BASED ON 19 STATIONS.
