1. ICME
  1.1. Catalog
	# Identified in ICME catalogs: Richardson & Can List
	RC catalog:
	Disturbance start time: 2013/02/13 17:00 UT
	Ejecta      start time:	2013/02/14 08:00 UT
	Ejecta      End   time:	2013/02/16 14:00 UT
	dv =  20 km/s, v =  360 km/s, vmax=  400 km/s
      	MC index: 0    
	Dst:       -37  nT
     	Suggested source CME: 
     	V_transit:   km/s
      
  1.2. SW Plots
	Overall ICME quality index: 3 
	SW type: EJ+SH
	ICME signatures: Bmax: 11.8 nT
			 irregular Bz variation
	Other ICME signatures: smoothly decreasing velocity; low plasma density; low proton temperature than the expected one
				low plasma beta
                     
	Peculiar behavior: Bz was almost constant (close to zero), high density and plasma beta in the middle.
                         
	Search Window:
	Upper bound: Disturbance speed 430 km/s: 97 hrs: 
	Lower bound: Transit speed < 700 km/s: 60 hrs <

2. CME
   2.1. A. Candidate A
	A.1. LASCO:
		#CME 2013/02/09 06:36 UT, partial halo (from CDAW)
		Major CME, moving toward north pole with linear velocity 617 km/s

	A.2. STEREO:
		Major CME in both COR2-A and COR2 B 
		moving in the frontside.

	A.3. AIA and GOES:
		corresponding flare: C2.4 on 2013/02/09 and peaked at 06:40 UT
		Filament eruption from decayed AR ~ N23W07

	A.4. Comment:
		Possible candidate of disturbance, however initial velocity was high.

   2.2. B. Candidate B
	B.1. LASCO:
		#CME 2013/02/12 23:12, partial halo (from CDAW)
		Major CME moving SW with very fast linear velocity of 1050 km/s

	B.2. STEREO:
		Observed in both COR2-A and COR2-B. LE was sharp in COR2-A, consistent with front side source.
		
	B.3. AIA and GOES
		corresponding flare: C5 on 2013/02/12, peaked at 23:35 UT
		Filament eruption from decayed AR ~ S36W50
	B.4. Comment:
		Unlikely the source of disturbance, considering the velocity of the CME.
