Bulletin

Solar activity has been very low, no flares in past 24 h. NOAA AR 2748 went from beta to alpha magnetic field configuration. Solar activity is expected to remain low.

No Earth directed CMEs in past 24 h. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 620 km/s with interplanetary magnetic field magnitude of 4 nT. The Earth is still inside the high speed solar wind from a positive polarity coronal hole. The solar wind speed ranged from 700 to 600 km/s in the past 24 h. Geomagnetic conditions were mostly unsettled to active both locally and at planetary levels (K Dourbes and Kp between 3 and 4), with an isolated peak of K Dourbes = 5 at 21:00 UT on September 2. Mostly unsettled conditions expected, active periods remain possible.

Today's estimated international sunspot number (ISN): 012, based on 15 stations.
