      MC index:     1

  1.2. Comments
      Overall ICME quality index: 2
      ICME signatures: Bz rotation
      Others ICME signature: no
      Not a typical ICME
      Peculiar behavior: increased temperature in the middle of structure
      Disturbance time:  300 km/s  -> searcher window: 139 hrs -> 2009/12/27 07 UT

2. CME
   2.1. A. Candidate A
    A.1. LASCO:    
      #CME a weak and extremely slow CME started at 2009/12/27 20:30 UT
           diffuse and faint CME with AW of ~ 30 deg, toward the right
      CME - CDAW: 2009/12/27 20:30 UT, vel - 90 km/s, PA=284 deg, AW = 63 dege	   
      CME - SEEDS: 2009/12/27 22:06 UT, vel - 124 km/s
     
    A.2 .STEREO: 
          a weak and extremely solow CME toward the left, not detected by SEEDS

    A.3. AIA & GOES
	   N/A

    A.4 Comment:  
	   Unlikey the source: this is not a halo CME seen either in LASCO not STEREO 
           Peculiar behavior: if it is the source, it must be in the streamter belt, spanning a wide longitude

  

   2.2. Comment
        not likely the source, but no other alternative
	Transient Time: 126 hrs
	Transit Velocity: 331 km/s


3. Other Comments
    No likely source. The canidiate A is unlikely, unless it is a blowout of streamer belt, narrow in latitudial direction, but wide in longitudial direction

4. Summary
    SW index:  2
    Source index: 3 
    Overall index: 3
