COMMENT: NOAA AR 2671 has again increased in size and produced C-class
flares, there were four in past 24 h. The strongest one did not originate
in NOAA AR 2671 though, it was a C4.4 peaking at 20:02 UT on August 18
and
came from a region rotating into view from the east limb. A CME erupted
in
the vicinity of this region (seen at 14:24 UT on August 18 by LASCO-C2),
directed to the east and will not be geoeffective. C-class (and possibly
M-class) flares can be expected
No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar
protons have remained at background levels over the past 24 hours.
The Earth is still inside a high speed solar wind stream, the speed is
around 680 km/s with interplanetary magnetic field intensity of 7 nT. As
a
consequence, Kp reached 5 and the local K went up to 4. More disturbed
conditions can be expected in the next 24 h.
TODAY'S ESTIMATED ISN : 051, BASED ON 23 STATIONS.
