2. CME
   2.1. A. Candidate A
    A.1. LASCO:    
      #CME 2011/03/03 06:12 UT, partial halo (from CDAW)
           partial halo CME towards the southern hemisphere

    A.2 .STEREO: 
           CME in COR2-A and COR2 B towards the southern hemisphere (first appearence at COR2 05:24 UT)
	   Front-side halo CME

    A.3. AIA & GOES
	   GOES doesn't give a flare at that time, but we see brightenings and dimmings at AIA wavelengths at the southern hemisphere

    A.4 Comment:  
	   Likely the source:  the eject is in the southern hemisphere and is in agreement with LASCO
