Working Group 1 (Coronal Mass Ejections), led by Jim Klimchuk and Joe Gurman, addressed three main questions during the SHINE 2000 meeting in Lake Tahoe:
Progress was made on all of these questions, especially the last (see below), but in the end it was clear that much more work needs to be done before definitive answers are available. This "work in progress" status is reflected in the three challenges that we set for ourselves for the coming year:
Model | Multi-polar | Flux Rope | Sheared NL | Converg. Flow | Recon. Timing | Recon. Location | Mass Distrib. |
---|---|---|---|---|---|---|---|
Breakout | Y | NR | Y | NR | at/before | above | NR |
Flux Rope | NR | Y | Y | Y1 | after1 | below | NR |
NR2 | at/after2 | ||||||
Tether Cutting | NR | NR | Y | NR | at/before | below | NR |
Flux Injection | NR | Y | NR | NR | NR | NR | NR |
Mass Loading | NR | NR | NR | NR | NR | NR | cavity and/or prominence |
