Bülletään

The solar activity has been quiet over the past 24 hours. The visible solar disc was spotless, and the X-ray flux remained below B-level. Flaring conditions is expected to remain at low levels.

No Earth directed coronal mass ejection has been observed. The greater than 10 MeV solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.

The solar wind speed ranged between 420 and 495 km/s over the past 24 hours. The total interplanetary magnetic field strength reached about 7.5 nT, and the southward magnetic component fluctuated between -6 and 6.3 nT. The solar wind parameters are expected to continue to be enhanced due to the solar wind streams associated with the patchy coronal hole (of negative polarity) that reached the central meridian on Feb 4.

With the arrival of the streams associated with the coronal hole, active geomagnetic conditions were observed. The Kp index ranged between 1-4 (NOAA) and the local K index 1-3 (Dourbes). The conditions are expected to remain unsettled with possible short periods of active conditions.
