Bülletään

The solar activity has been quiet over the past 24 hours. The visible solar disc is spotless and no significant flare has 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 reached about 440 km/s on July 13 around 11:00-12:00 UT and decreased to about 325 km/s, the total interplanetary magnetic fields remained below 3 nT, and the southward magnetic component varied between -2 and 2.5 nT. Solar wind parameters are expected to remain at nominal levels for the next 24 hours. The fast solar wind associated to the coronal hole that reached the central meridian on July 11 is expected to reach Earth on July 14 around midnight, which will enhance the solar wind parameters.

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 with to the arrival of the high speed solar wind associated with the coronal hole.
