2. CME
   2.1.A.  Candidate A
    A.1. LASCO:
      #CME 2009/06/23 00:00 UT, full halo CDAW
	   A full halo CME can be seen from CDAW at this point in time. it is not detected and labeleled like some others though.
     A.2. STEREO:
	    STEREO A strongly confirms an earthbound nature to this CME, and though the STEREO B data does not label the CME that may be observed coming from that point on the sun, the shape of an outflow can be observed at the proper time and direction to correspond to an earthward CME.

     A.3. AIA & GOES:
	    
     A.4. Comments:
             This is by far the most likely source for this CME


   2.2 Decided Source
       The most likely solar source is Candidate A.
