Bülletään

No active regions visible on the disk. Solar activity has been very low, no flares in the past 24 h. Low solar activity expected.

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 410 km/s with interplanetary magnetic field magnitude of 5 nT. Geomagnetic conditions reached active levels overnight for one time period, both locally with k = 4 at 22:00 UT and planetary with Kp=4 at 00:00 UT. The solar wind measured by ACE shows signs of a possible interaction between the CME from October 25 and the compression region ahead of the high speed stream from a negative polarity coronal hole. The interplanetary magnetic field reached 17 nT with weak southward components, the solar wind speed reached 450 km/s. The coronal hole is composed of small patches which can still affect the Earth in the coming days. Geomagnetic activity is expected to be quiet to unsettled (with possible active periods).
