Bulletin

NOAA AR 2671 continued producing C-class flares, whereas the region rotating into view produced an M1.1 flare peaking at 01:52 UT. More M-class flaring (and possibly X) 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 700 km/s with interplanetary magnetic field intensity of 4 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 international sunspot number (ISN): 059, based on 18 stations.
