Event Details Result on 2011/12/20 Gopal, Hong, Cho, Pertti, Seiji, and Akiyama discussed this solar source. This is difficult event because of three possible solar sources. Drop this event because of the large uncertainty. ******Previous Memo********************************* CME association has less confidence, i.e., other possible candidate CMEs exit. Therefore we picked up three possible cadidates and listed informations to compare them. #22.1 CME is faint and norrow (AW~40). Moreover solar source is a small bright points (inclued jet-like feature and dimming) and isn't good candidate. Akiyama picked #22.2 and #22.3 up. #22.2 CME is also faint and narrow (AW64). We can see two filament eruptions (S15E20 and S21E17) at each different neutral lines observed by EIT and HIDA/FMT Ha movie. #22.3 CME is wider (AW118) than others and shows some loop brightnings at AR9114 (N11E17). But there is not clear eruptive signatures (only small jets). Moreover we can see a backside CME signature (faint dark moving material) over the limb (PA116) at 2000/08/07 03:21. So this CME may be (or include) a backside CME. Need to discussion again. **************************************************** From Nitta's E-mail (2011/09/26 3:48 PM) when I looked at data for event #22, they somehow looked familiar. Yes, this was one of the events in Jie Zhang paper in 2007, where we could not convincingly identify the solar source (confidence level 3). So I now wonder what you have done to improve the identification of the solar source for the following events since Jie's paper. Most of them are confidence level 3 events. #22, 24, 25, 27, 30, 54. I appreciate it if you let us know how you have picked up one of the possibilities. 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.)
