  1.2. Comments
      Overall ICME quality index: 3
	  SW type: MC
      ICME signatures: Bmax: 15.6 nT
                       Bz rotation
		       			
			
      Others ICME signature: low proton temperature, and low plasma density.

      Peculiar behavior: velocity was increasing in the middle and high plasma density, it was 16.2 cm^-3 in the center
                         

      Based on 390 km/s  -> search window 106.5 hrs or 4 1/2 days-> 2012/01/13 05:30 UT

2. CME
   2.1. A. Candidate A
    A.1. LASCO:    
      #CME 2013/01/13 12:00 UT, partial halo (from CDAW)
           angle- 176, velocity- 229 km/s
			Seeds vel C2: 167 km/s
	   Distinctive LF and unidentifiable core

    A.2 .STEREO: 
           Seen as a major CME in both COR2-A and COR2 B
	   Front-side halo CME, consistent witht the flare source region

    A.3. AIA & GOES
	   corresponding flare: M1.7 at 2013/01/13 08:35 UT
	                        flare from AR 11652 at N17W22

    A.4 Comment:  
	   likey the source: the ejecta is in the nother-west quadrant
	                       the ejecta does cross the equator in STEREO FOV
			       the ejecta cross the northern-pole in LASCO FOV
           Peculiar behavior: Eruption started at 08:35 UT on 2013/01/13 as seen from AIA.

	


   2.1. B. Candidate B
	B.1. LASCO:
			#CME 2013/01/14 09:24, partial halo (from CDAW)
			moving with 264 km/s
	B.2. STEREO:
			CME was not moving in the front side.
	B.3. AIA and GOES:
	B.4. Comments:
      		Due to direction of propagation, unlikely the source.

  2.1. C. Candidate C
	C.1. LASCO:
			#CME 2013/01/15 08:12, poor event (from CDAW)
			slow CME with linear velocity of 221 km/s and angular width of 105.
			Leading front was not sharp.
	C.2. STEREO:
		Seen as front side moving CME in both COR2-A and COR2-B. 

	C.3. AIA and GOES:
			Associated with M-class flare, peaked at 06:58 UT, from AR 11650

	C.4. Comments:
		located at the SE quadrant, unlikely to be the source due to small velocity and direction.

  2.1. D. Candidate D
	D.1. LASCO:
			#CME 2013/01/15 19:48, partial halo (from CDAW)
			moving with velocity of 798 km/s.
	D.2. STEREO:
		moving northward, unlikely the front side moving CME.
	D.3. AIA and GOES:
	D.4. Comments:
		Unlikely the source of disturbance. 

  2.1. E. Candidate E
	E.1. LASCO
		#CME 2013/01/16 19:00 UT, partial Halo (from CDAW)
			Fast CME with linear velocity 648 km/s.
			Sharp LE, crossed the equatorial line.
	E.2. STEREO
		Seen as major CME in COR2-A and COR2-B.

	E.3. AIA and GOES:
		 AIA data is not available.
	
	E.4. Comments:
		less likely be the source of disturbance because of time of eruption.
