Bulletin

The solar activity has been quiet over the past 24 hours: the visible solar disc is spotless and no significant flares have been recorded. Quiet flaring conditions are expected for the next 24-hour period.

No Earth directed Coronal Mass Ejection has been observed. The solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.

The solar wind speed ranged between 380 and 420 km/s, the total interplanetary magnetic fields remained below 6 nT, and the southward magnetic component varied between -4 and 3.5 nT. A north pole coronal hole (of positive polarity) that extended up to latitude -15 degree, reached the central meridian on July 11. The fast solar wind associated to this coronal hole is expect to reach Earth on July 15 early in the day.

The geomagnetic conditions were quiet and it is expected to remain quiet as the Earth remains in the slow solar wind speed regime. Enhancement of the geomagnetic conditions are expected on July 14 due to the arrival of the high speed solar wind.
