2. CME
   2.1. A. Candidate A
  	A.1. LASCO:
		#CME 2013/06/22 at 12:00 UT, partial halo (from CDAW)
		major CME moving with velocity of 357 km/s
	A.2. STEREO:
		Halo CME in COR2-A and partial halo in COR2-B. From the direction in COR2-B, does not
		look like it was travelling to the front side.
	A.3. AIA and GOES:
		
	A.4. Comment:
		unlikely the source. 

  2.2. B. Candidate B
  	B.1. LASCO:
		#CME 2013/06/22 at 18:24 UT, partial halo (from CDAW)
		CME moving with velocity of 477 km/s
	B.2. STEREO:
		Was not moving in the front side.
	B.3. AIA and GOES:
		
	B.4. Comment:
		unlikely the source. 


  2.3. C. Candidate C
  	C.1. LASCO:
		#CME 2013/06/23 at 22:36 UT, partial halo (from CDAW)
		CME moving with velocity of 174 km/s
	C.2. STEREO:
		CME was moving in the frontside
	C.3. AIA and GOES:
		corresponding to M2.9 flare, started at 2013/06/23 20:48 UT
		Related to AR 11778, located near S18 E63.
	C.4. Comment:
		unlikely the source, because of direction and velocity. 


  2.4. D. Candidate D
  	D.1. LASCO:
		#CME 2013/06/24 at 04:00 UT, halo (from CDAW)
		major CME moving with velocity of 709 km/s
	D.2. STEREO:
		halo CME in COR2-A and partial halo in COR2-B, seem like not moving in the front side. 
		The direction of the nose of the CME suggest that the source was located near western limb.


	D.3. AIA and GOES:
		stealth CME. possibly filament eruption from the SW hemisphere, small C class flare was observed.
	D.4. Comment:
		This high speed CME was not associated with M or X class flare, may be the source was behind the 
		Sun. It is hard to be the source of disturbance on 20130627. 
		eruption around same time is visible in stereo-A 195 euvi. 


  2.5. E. Candidate E
  	E.1. LASCO:
		#CME 2013/06/25 at 11:12 UT, halo (from CDAW)
		major CME moving with velocity of 709 km/s
	E.2. STEREO:
		halo CME in COR2-A and partial halo in COR2-B, seem like not moving in the front side. 
		The direction of the nose of the CME suggest that the source was located near western limb.


	E.3. AIA and GOES:
		stealth CME. possibly filament eruption from the SW hemisphere, small C class flare was observed.
	E.4. Comment:
		This high speed CME was not associated with M or X class flare, may be the source was behind the 
		Sun. It is hard to be the source of disturbance on 20130627. 
		eruption around same time is visible in stereo-A 195 euvi.
