NOTE: the above forecasts are valid from 1230UT, 17 Aug 2017 until 19 Aug
2017
PREDICTIONS FOR 17 Aug 2017 10CM FLUX: 077 / AP: 032
PREDICTIONS FOR 18 Aug 2017 10CM FLUX: 080 / AP: 021
PREDICTIONS FOR 19 Aug 2017 10CM FLUX: 082 / AP: 007
COMMENT: NOAA AR 2671 continued to grow and has evolved into a beta-gamma-
delta magnetic field configuration. Nevertheless, it has not produced any
flare above the B-class level in past 24 h. The situation can change as
this region will likely generate C-class flares, and has potential for
M-
(and even X-) class flares. It produced a CME directed to the west first
seen at 14:00 UT (LASCO-C2) on August 16, that will most likely miss the
Earth.
No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar
protons have remained at background levels over the past 24 hours.
Geomagnetic conditions have been disturbed due to the expected arrival
of a
high speed stream from a coronal hole (Kp reached 5 at 06:00 UT and the
local K went up to 4 at 09:00 UT). Solar wind speed is increasing and
currently around 550 km/s with interplanetary magnetic field intensity
of
11 nT, with periods of negative Bz since early today. More disturbed
conditions are expected in the next 48 h with K up to 6.
TODAY'S ESTIMATED ISN : 040, BASED ON 19 STATIONS.
