Bülletään

Solar activity was very low with only a single B1.6 flare peaking at 05:20UT from Catania sunspot group 86 (NOAA active region 2713). This is the only spotted region on the visible disk and it is in decay. Chances for C class flaring remain very low.

No Earth directed CMEs were observed in coronagraph images.

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

Solar wind conditions have been nominal with solar wind speed around 300 km/s and total magnetic field below 5 nT. The Bz component of the magnetic field was variable. The magnetic field phi angle indicates a negative sector connection. Solar wind conditions are expected to remain nominal in the next 48 hours with afterwards an expected sector change and an increase in solar wind speed associated to the positive polarity coronal hole in the northern hemisphere that has passed the central meridian yesterday.

Geomagnetic conditions were quiet to unsettled (local K Dourbes 0-3 and NOAA Kp 1) and are expected to remain quiet in the next 48 hours.
