Bulletin

NOAA AR 2671 has reduced its complexity (now has beta-gamma magnetic configuration) and decreased in size, it has not produced any flare above the B-class level in the last 48 h. The situation can change as this region can generate C-class flares, and has potential for M-class flares.

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 inside a high speed solar wind stream, the speed is around 600 km/s with interplanetary magnetic field intensity of 6 nT. Kp reached 5 and the local K went up to 4, on August 18. More disturbed conditions can be expected in the next 48 h.

Today's estimated international sunspot number (ISN): 042, based on 15 stations.
