In the last 24 hours Solar activity reached moderate levels. Region 4384 produced an M1.2 to SF flare at 13 to 0955 utc, the strongest ofthe period. The region continued to increase in area in its intermediateand trailer spots as it approached the W limb. Decay was observed inRegions 4388 and 4387 . Only minorchanges were observed in the remaining spotted active regions. Other activity included a large filament eruption in the southernhemisphere. It began slowly lifting off after ~12 to 2100 utc. SubsequentSOHO to LASCO C2 coronagraph imagery contained a coronal mass ejection signature to the SWbeginning at 13 to 0036 utc. Analysis and modeling of the event suggestedthe ejecta would pass below Earths orbit. No other potentiallyEarth-directed coronal mass ejections were observed in available coronagraph imagery. Solar activity is expected to be at low levels, with a chance forM-class flares over 13 to 15 march.

In the last 24 hours The greater than 2 mega electron volt electron flux reached high levels with a peakflux of 2, 940 pfu observed at 12 to 1545 utc. The greater than 10 mega electron voltproton flux was at background levels. The greater than 2 mega electron volt electron flux is expected to reach high levels on 13 Mar, moderate levels on 14 Mar, and high levels again on 15 march. Thegreater than 10 mega electron volt proton flux is expected to continue at backgroundlevels through 15 march.

In the last 24 hours Solar wind parameters contained enhancements after ~13 to 0500 utc. Totalmagnetic field strength increased to a peak of 13 nano tesla and Bz rotated asfar south as to 8 nano tesla. Solar wind speeds increased from ~400 kilometers per second to ~500 kilometers per second beginning after 13 to 0830 utc. Phi angle transitioned from negativeto positive at 13 to 0854 utc. Enhanced solar wind conditions are expected to prevail through 15 Mardue to positive polarity coronal hole high speed stream influences.

In the last 24 hours The geomagnetic field was at quiet to G1 geomagnetic stormlevels. Periods of G1 geomagnetic storming are expected on 13 to 14 Mar, with active conditions likely on 15 Mar, due to positive polarity coronal hole high speed streaminfluences.
