Bülletään

No active regions visible on the disk. Solar activity has been very low, no flares in the past 24 h. The situation is not expected to change in the next 48 h.

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 500 km/s with interplanetary magnetic field magnitude of 5 nT. Geomagnetic conditions were mostly quiet to unsettled, K and Kp reached 4 briefly (at 03:00 UT for Kp and at 07:00 UT for K Dourbes) due to slightly high speed solar wind (~550 km/s) with negative Bz (up to -5 nT) lasting for several hours. The fast solar wind stream associated with a negative polarity coronal hole is expected to arrive to the Earth on September 7. Unsettled to active geomagnetic conditions can be expected.
