Event Details
This is difficult event to find solar sources. According to SXT, EIT, and several Ha images (BBSO), CME has multiple solar sources with AR 9218, 9212, and 9213. Specifically, AR 9213(N02W02) and AR 9218 (N25E17) shows faint arcade loops and dimmings observed by EIT.
Anyway, we see two dimmings at over the NE limb (19:25 BL051) and SW limb (19:13 BL202). These dimmings are associated with other two backside CMEs.

Dear Masha,
Thanks for sending your active region identifications to us. For the past couple of days, Seiji, Hong, Pertti, Sachiko and me were reviewing all the CDAW events. We mostly agree. The disagreement seems to be mostly regarding filament eruption events (marked EP) in the Table. The active region you identifies for the EP events are generally located at one end of the filament. Here are some specific events where there was disagreement and what we found.
#27
Soft X-ray images from Yohkoh/SXT shows that the post eruption arcade is over three active regions 9218, 9212, and 9213.
