2. CME
   2.1. A. Candidate A
 	A.1. LASCO:
		#CME 2013/04/26 at 18:24 UT, partial halo (from CDAW)
		CME moving southward at a linear speed of 271 km/s
	A.2. STEREO:
		CME with clear edge, moving front-side.
	A.3. AIA and GOES
		Filament eruption, large filament extending from northern hemisphere to southern hemisphere. 
	A.4. Comment:
		Possible source.

  2.1. B. Candidate B
	B.1. LASCO:
		#CME 2013/04/28 13:25 UT,  partial halo (from CDAW)
		CME moving with a linear speed of 400 km/s
	B.2. STEREO:
		CME was not moving in the fron side
	B.3. AIA and GOES:
		eruption from the eastern limb (southern hemisphere)
	B.4. Comments:
		Unlikely the source because of direction.

  2.1. C. Candidate C
	C.1. LASCO:
		#CME 2013/04/28 20:48 UT, with angular width 91 (from CDAW)
		moving with linear speed 497 km/s
	C.2. STEREO:
		front side moving CME.
	C.3. AIA and GOES:
		Eruption near the western limb, southern hemisphere
	C.4. Comments:
		Unlikely the source because of the location of the erupting site.


   2.1. D. Candidate D
 	D.1. LASCO:
		#CME 2013/04/29 at 03:24 UT, partial halo (from CDAW)
		CME moving with a linear speed of 279 km/s
	D.2. STEREO:
		CME is not moving front-side.
	D.3. AIA and GOES
	D.4. Comment:
		not the source because of the direction.

  2.1. E. Candidate E
	E.1. LASCO:
		#CME 2013/04/29 06:24 UT, with angular width 67 (from CDAW)
		moving with a linear velocity of 452 km/s
	E.2. STEREO:
		Front side moving CME. Mostly northward directed, didn't cross the equator.
	E.3. AIA and GOES:
	E.4. Comments:
		Unlikely the source because of the direction.
