On the three-dimensional configuration of coronal mass ejections (2004, background): “…signatures of CMEs, like: outward motion of coronal material in form of loops or eruptive prominences (e.g. Webb & Hundhausen 1987), flares (Hudson et al. 1998), coronal waves and dimmings (e.g. Thompson et al. 1998) or post-eruptive loops/arcades (Sterling et al. 2000; Tripathi et al. 2004).”
The Coronal Mass Ejection of 1998 April 20: Direct Imaging at Radio Wavelengths (2001, background): “…and continua; e.g., review by Pick 1999 and references therein), EUV (dimmings, Moreton waves; e.g., Thompson et al. 1999; Klassen et al. 2000; Delanne´e 2000), and soft X-ray (SXR) wavelengths (dimmings, morphological changes; e.g., Hudson et al. 1998; Zarro et al. 1999; Sterling et al. 2000).”
Interaction of EIT Waves with Coronal Active Regions (2001, background): “Note the sigmoid structure of the field reminiscent of the observed active regions most likely to erupt (e.g., Sterling et al. 2000).”
Eruption of a Buoyantly Emerging Magnetic Flux Rope (2003, background): “In addition, sigmoids seen before CME initiation often become brighter when the CME erupts (Sterling et al. 2000).”
Interplanetary flux rope ejected from an X-ray bright point. The smallest magnetic cloud source-region ever observed (2005, background): “However, in some cases, sigmoids do appear in EUV images (see e.g. Sterling et al. 2000).”
Onset of the Magnetic Explosion in Solar Flares and Coronal Mass Ejections (2001, methodology): “This sigmoidto-arcade transformation is compatible with the standard model for ejective two-ribbon Ñares (Sterling et al. 2000).”
