Bulletin

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 400 and 470 km/s over the past 24 hours. The total interplanetary magnetic field strength was about 8 nT in the beginning of the period, then decreased to values below 5 nT. The southward magnetic component fluctuated between -6 and 6 nT. The high-speed stream associated with the large patchy coronal hole that reached the central meridian on Feb 4 may is expected to enhance further the solar wind parameters on Feb the 8th.

The geomagnetic conditions were quiet with several periods of unsettled activity. The Kp index ranged between 0-3 (NOAA) and the local K index 0-3 (Dourbes). The conditions are expected to remain mostly quiet with possible unsettled conditions periods for the next hours, then active conditions with short periods of minor storm is expected due to the arrival of the high-speed stream associated with the coronal hole that reached the central meridian on Feb 4.
