CMEs in Soft X-rays, impulsive flares, and
homology

• Early SXT literature by Uchida et al., Klimchuk
  et al, Hudson et al., Manoharan et al., Nitta
  Akiyama
• N.V. Nitta and H.S. Hudson, GRL 28, 3801 (2001)

Six CMEs from AR 9236, 24-26 November 200
3
Six M or X flares, five of them impulsive
4
Magnetic configurations of the flares and
homology (contours HXT)
5
Magnetic fluxes (MDI) in AR 9236

Remarks

• 5/6 of these CMEs definitely were associated with
  impulsive flares, not LDEs
• The flares showed homology, and perhaps this
  could be explained by persistent flux emergence
• The CMEs showed homology, and I cannot think of
  any explanation for this
