Bulletin

Solar activity was low with X-ray flux remaining below B level. The last spot within Catania group 9 (NOAA region 2734) was disappearing as the region is rotating further towards the West limb. With a spotless disk, X-ray flux is expected to remain below C level.

No Earth directed CME's have been detected in coronagraph data.

The Solar proton flux levels were at background values and are expected to remain so.

Solar wind quickly recovered from yesterdays CME passage with Solar wind speed around 330-370 km/s throughout the period. Total magnetic field decayed from near 7nT to around 4 nT currently and the magnetic field phi angle settled again in the negative sector. There is a slight possibility of some enhancements due to the March 9 CME late today or early tomorrow but otherwise nominal solar wind conditions are expected over the next 24 hours with later on March 14 an expected onset of a high speed stream from the equatorial coronal hole that passed central meridian late March 10.

Geomagnetic conditions were quiet to unsettled (local K Dourbes 1-3 and NOAA Kp 1-2) but could reach active conditions in the 24-48 hour time frame due to the expected high speed stream.

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 000, na základě 13 stanic.
