	Disturbance start time: 2013/04/30 09:49 UT
	Ejecta      start time:	2013/04/30 12:00 UT
	Ejecta      End   time:	2013/05/01 07:00 UT
	dv =  50 km/s, v =  400 km/s, vmax=  430 km/s
      	MC index: 2    
	Dst:       -47  nT
     	Suggested source CME: 
     	V_transit:   km/s
      
  1.2. SW Plots
	Overall ICME quality index: 3
	SW type: MC+SH
	ICME signatures: Bmax: 11.1 nT
			 Smoothly changing Bz.
	Other ICME signatures: decreasing velocity, and low plasma beta
                     
	Peculiar behavior: plasma density was high and proton temperature was low only in the begining.
                         
	Search Window:
	Upper bound: Disturbance speed 400 km/s: 104 hrs:
	Lower bound: Transit speed < 700 km/s: 60 hrs <
