     	V_transit:    km/s
      
  1.2. SW Plots
	Overall ICME quality index: 3 
	SW type: EJ+SH
	ICME signatures:  Bmax: 8.8 nT 
			  varying Bz, but variation wasn't smooth.
	Other ICME signatures:  decreasing velocity, and low proton temperature.
                     
	Peculiar behavior: high plasma density and plasma beta. 
                         
	Search Window:
	Upper bound: Disturbance speed 470 km/s: 89 hrs:
	Lower bound: Transit speed < 700 km/s: 60 hrs <

2. CME
   2.1. A. Candidate A
   	A.1 LASCO:
		#CME 2013/08/17 at 19:12 UT, halo (from CDAW)
		moving with a velocity of 1202 km/s
	A.2 STEREO:
		halo CME in COR2-A and COR2-B.
	A.3 AIA and GOES:
		corresponding to M3.3 class flare peaked at 18:24 UT
		from AR 1818 at a location S04W30.	

	A.4 Comment
		Unlikely the source because of velocity.


  2.2. B. Candidate B
	B.1 LASCO:
		#CME 2013/08/19 23:12, halo (from CDAW)
		moving with a velocity of 877 km/s.

	B.2 STEREO:
		halo in COR2-A and partial halo in COR2-B.

	B.3 AIA and GOES:
		source region is unidentifiable, may be located on the back-side. 
	B.4 Comment
		unlikely the source due to direction. source is in backside (stereo-A 195 )



  2.3. C. Candidate C
	C.1 LASCO:
		#CME 2013/08/20 08:12, halo (from CDAW)
		moving with a velocity of 602 km/s.

	C.2 STEREO:
		moving in the frontside, southward

	C.3 AIA and GOES:
		filament eruption in the southern hemisphere, region was near the western limb
	C.4 Comment
		because of the location of the erupting region and the direction it is less
		probable that it was the source of the disturbance.



  2.4. D. Candidate D
	D.1 LASCO:
		#CME 2013/08/21 05:12, partial halo (from CDAW)
		moving with a velocity of 385 km/s.

	D.2 STEREO:
		major CME moving in the front side.

	D.3 AIA and GOES:
		AIA data is not available in jhelioviewer.
	D.4 Comment
		unlikely the source due to speed.
