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.
