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 (Kp=5
during 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.
