Chertok, I.M., Grechnev, V.V., Hudson, H.S. and Nitta, N.V. (2004). Homologous large-scale activity in solar eruptive events of 24–26 November 2000. Journal of Geophysical Research 109: doi: 10.1029/2003JA010182. issn: 0148-0227.

We study large-scale activity on the solar disk associated with a 24--26 November 2000 series of six recurrent major flares and halo coronal mass ejections (CMEs). The analysis is based mainly on the SOHO/EIT data, particularly by using properly rotated difference full-disk images with 12-min intervals at 195 ¿ as well as with 6-hour intervals at 171, 195, 284, and 304 ¿. We demonstrate that these eruptive events were homologous not only by their flare and CME characteristics, as Nitta and Hudson <2001> showed, but also in terms of their large-scale CME-associated manifestations in the EUV corona. These include long and narrow channeled dimmings, some transequatorial; anisotropic coronal waves, propagating in a restricted angular sector; and additional quasi-stationary emitting fronts. As a whole, in all of these six events, the homologous CME-associated disturbances covered a considerable portion of the solar disk. The homology tendency appears to be due to significant disturbance, partial eruption, and relatively fast restoration of the same large-scale structures involved in the repeating CME events. We briefly discuss the implications of the analysis in connection with the nature of coronal equilibrium.
