Bulletin

Over the past 24 hours solar activity has been low. No flares have been recorded. A recurrent unnumbered Active Region at the the East limb has some potential to produce flaring activity. The greater than 10MeV proton flux remained at background levels over the past 24 hours. No Earth directed CMEs were detected. Solar activity is expected to remain low over the next 24 hours. The solar wind parameters variations are still disturbed since 12:00 UT (10 July) due to ICME arrival most probably produced by a filament eruption on July 5. The Earth is still inside a magnetic cloud. The solar wind speed has increased from 350 till 435 km/s over the past 24hrs. The total magnetic field strength has fluctuated mainly between 9.3 and 3 nT. Bz component has fluctuated between -7 and +6 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be at unsettled to active levels today and tomorrow.

Today's estimated international sunspot number (ISN): 000, based on 24 stations.
