The solar activity has been quiet over the past 24 hours. The unique sunspot group on the disc (Catania sunspot group 9, NOAA Active Region 2734) continued to decay and did not produce any flare. The X-ray flux remained below B-level and the solar activity is expected to remain at low levels.

A Coronal Mass Ejection (CME) has been observed in SOHO/LASCO-C2 on March 8 at 22:12 UT. Its projected principal components (in the plane of the sky) was South-East. No source region was identified on the solar disc that faces Earth, therefore, this CME is believed to be back side, and probably associated with a filament as no active region is observed on STEREO/EUVI-A images. 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 parameters continued to be slightly enhanced during the last 24 hours due to several small patchy equatorial coronal holes. The solar wind speed ranged between 400 km/s and 450 km/s. The total interplanetary magnetic field strength remained below 7 nT. The Bz component fluctuated between -4.5 nT and 4.7 nT. The slightly enhanced solar wind parameters are expected to persistence for more days, due to all those small patchy equatorial coronal holes on the surface of the sun.

The geomagnetic conditions were quiet to unsettle over the past 24 hours, with K-index (Dourbes) ranging from 0 and 3, and Kp (NOAA) ranging from 0 and 2. The geomagnetic conditions are expected to be mainly quiet, but in response to the slightly enhanced interplanetary magnetic field and possible prolonged period of southward directed Bz component, sort period of unsettled conditions may also occur.
