The solar activity has been slightly more active over the past 24 hours. One C-class flare (C1.3) has been observed from Catania sunspot group 9 (NOAA Active Region 2734) peaking at 03:19 UT on March 08. After this flare, the X-ray flux returned below B-level, and the sunspot is now decaying . The solar activity is expected to remain at low levels with a very small chance of C-class flare.

The C-class flare was associated with a coronal dimming. Although no clear halo Coronal Mass Ejection is been observed, we do predict Earth-directed component of this relatively slow speed Coronal Mass Ejection. Further information will come later as data will come. 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-hour due to several small patchy equatorial coronal holes. The solar wind speed re-increased and reached about 500 km/s around 15:00 UT on March 15. The total interplanetary magnetic field strength ranged between 5 nT and 8 nT. The Bz component fluctuated between -7.3 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) and Kp (NOAA) ranging from 1 and 3. In response to the slightly enhanced interplanetary magnetic field and possible prolonged period of southward directed Bz component, the geomagnetic conditions are expected to remain quiet to unsettle.
