Gopal, Hong, Cho, Pertti, Seiji, and Akiyama discussed this solar source. There is no need for concern about #54.2. We selected that #54.1 CME was most possibility. But eruptive filament of #54.3 was also interest information. Therefore #54.3 event remained at memo as a reference database.
******Previous Memo*********************************
#54.1 CME is a faint halo. #54.2 flare may be merges or follows with #54.1 CME in IP medium.
Akiyama carefully checked other source candidates, because Marubashi and Cho pointed out the possibility of mistake. She added #54.3 up again. #54.3 was rejected previously due to too west location (N13W29). But she found that #54.3 also has a eruptive filament (N17W11). This is enough information as a MC candidate.

From Marubashi's E-mail (2011/10/04 AM3:30)
I just found two events for which the source identifications should be changed I believe. Because the number of events is small, I decided to circulate the information with in the text of this e-mail. (My selections are mainly based on the geometrical relationships between MC axis and the magnetic neutral line in the solar source region: parallelism between the two and the magnetic chirality agreement.)
(2) event # 54
shock detected by ACE: 2005/05/20/03:15
MC: 05/20/19:00 - 05/21/06:10
Source Proposal: CME 2005/05/16/13:50, width = 140,Flare, 12:46 (onset), C1.2, N16W27
Nuetral line in the source region is nearly parallel to the torus-fitted MC (L-handed)
Yellow contours are a neutral line under flare loop.
Yellow contour is a flare brightning area.
Yellos contours are a neutral line under flare loop (right side) and eruptive filament (left side).
