    CDAW gives a partial halo CME on 2011/11/08 at 11:36:05 UT, while GOES and Solar Monitor don't give an event at that time. There are small dimmings around AR11339 and AR11344 though. 

    CDAW also gives a partial halo CME on 2011/11/08 at 06:12:06 UT, but it seems that is a back-side event.


2.1. B. Candidate B
    B.1. LASCO:    
      #CME 2011/11/08 	00:00:06 UT, partial halo CME
           

    B.2. STEREO: 

           front-side CME, data from COR2-A and COR2-B, first frame at COR2-A 2011/11/08 00:24 UT

    B.3. AIA & GOES
	   GOES: no flare associated 

           Solar Monitor: AR11339, N19W09, class: C2.3 at 00:13 UT

    B.4 Comment:  

           Small dimmings around AR11339
