Event Details Result on 2011/12/20 Gopal, Hong, Cho, Pertti, Seiji, and Akiyama discussed this solar source. We decided to select #12.2 filament disappearance (N13E24) at 1999/08/02 06:12 as a most possibility of the solar source (#12.2 → #12). #12.1 event was remained as a reference data. Conclusively, this event was rejected from the list, because solar source located in over E15. ******Previous Memo********************************* CME associated with MC is low confidence. There are two candidates. CME of #12.1 listed in Gopalswamy et al (2008) is faint and narrow (AW59). Solar source is a small C4.0 flare in AR 8651 (N23W04). Therefore it is not good candidate for MC. The helicity sign between photosphere and MC don't correspond. Akiyama select #12.2 CME as a 2nd candidate. This is a partial halo based on a filament disappearance observed by Hiraiso and OACt Ha images. X-ray intensity of arcade loop is less than C1 (background level). The helicity sign between photosphere and MC is the same. In my feeling, #12.2 is most possibility as a MC's candidate. Need to disscuss them. **************************************************** From Nitta's E-mail (2011/09/26 01:15 AM) #12 Disagree. The selected CME is not clear, and the source region is also unclear. This can be a problem event, which is probably a stealth CME nearly in Sun Earth line. | ||||||||||
