Bulletin

Solar X-ray flux remained below background (B) level. With no active regions on disc, solar flaring activity is expected to be very low.

There are no Earth directed CMEs observed in coronagraph data.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux remained below the 1000 pfu event threshold and is expected to remain below that threshold over the next 24 hours. The 24h electron fluence was at nominal levels and expected to be nominal over the next days.

Solar wind values reflected background slow Solar wind conditions. Solar wind speed was mostly in the 300-330 km/s range. The interplanetary magnetic field was around 5nT (3.5-7nT), with a variable Bz component not reaching below -3nT. The magnetic field phi angle was stable in the negative sector (towards the Sun). Today a switch into the positive sector (away from the Sun) is expected and some increase in Solar wind conditions related to a positive polarity coronal hole is likely.

Geomagnetic condition were quiet (NOAA Kp 0-1 and local K Dourbes 0-2). An increase to unsettled conditions is expected with also an isolated active period not excluded.
