2. CME
    2.1, A, Candidate A
     A.1. LASCO  
       #CME 2011/10/27 	12:00:06 UT, halo CME (from CDAW)
           

     A.2. STEREO
         front-side CME, first COR2-A image at 12:24 UT 

     A.3. AIA & GOES
          #GOES and Solar Monitor don't give a flare at that time. Looking at AIA observations in different wavelengths, we can see that there was a filament eruption at the nothern hemisphere. The orientation and the timing of the eruption and the halo CME match. We can't see dimmings at the location of the filament.

	
     A.3. Comment
          Could be the source: The timing and orientation is in agreement with the observations
