Bulletin

The solar activity was at low levels over the past 24 hours. The sun is spotless and the X-ray flux is below B-level. The solar activity is expected to remain at low levels for the next 24 hours.

No earth-directed coronal mass ejections (CMEs) have been observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal values.

The solar wind conditions remained slightly enhanced over the past 24-hour due to the equatorial coronal hole (negative polarity and facing Earth on February 27): the solar wind speed ranged between 379 km/s to 473 km/s, the total interplanetary magnetic field remained below 6 nT, the southward component fluctuated between -4 nT and 3 nT. The solar wind conditions are expected to remain slightly enhanced for the next 24-hour. Then, new enhancement of the solar wind conditions is expected due to the influence of, first, the relatively small positive polarity equatorial coronal hole that reached the central meridian on March 1, and then, the southern coronal hole extension (negative polarity).

The geomagnetic conditions were quiet with few short periods of unsettle condition observed in Dourbes station (K-Dourbes = 3). We expect the geomagnetic conditions to remain mostly quiet with some short sporadic periods of unsettled condition for the next days due to the influence of the coronal hole high-speed streams.

Today's estimated international sunspot number (ISN): 000, based on 10 stations.
