NOTE: the above forecasts are valid from 1230UT, 22 Aug 2017 until 24 Aug
2017
PREDICTIONS FOR 22 Aug 2017 10CM FLUX: 087 / AP: 027
PREDICTIONS FOR 23 Aug 2017 10CM FLUX: 088 / AP: 010
PREDICTIONS FOR 24 Aug 2017 10CM FLUX: 087 / AP: 007
COMMENT: Active Region (AR) 2671 (McIntosh class: Fkc; Mag.type: Beta-
Gamma) and AR 2672 (McIntosh class: Dao; Mag.type: Beta) produced three
C-class flares during the past 24 hours. The largest flare was C3.0 flare
peaking at 17:57 UT yesterday. No Earth directed Coronal Mass Ejections
(CMEs) have been detected. The greater than 10MeV proton flux remained
at
background levels over the past 24 hours. There are no potentially
geoeffective coronal holes on the Sun. More C-class flares are expected
over the next 24 hours with some probability of M-class flares.
Solar wind parameters are still under influences of a coronal hole high
speed stream (CH HSS). During the past 24 hours solar wind speeds remained
stable around 600 km/s with two brief increases till around 670 km/s
(22:30 UT yesterday and 07 UT today). Total filed strength increased till
9nT at 02 UT today, simultaneously the Bz component reached a maximum
southward deflection of -9 nT. The interplanetary Kp index increased from
3
till 6 reaching moderate storm level (00-03 UT), minor storm level (Kpduring
03-06UT). Later Kp index returned to quiet conditions again. The
local station at Dourbes reported values of up to K=4. Next two days active
geomagnetic conditions can be expected, isolated episode of minor
geomagnetic storm is not excluded.
TODAY'S ESTIMATED ISN : 061, BASED ON 21 STATIONS.
