TL;DR: The Extreme Ultraviolet Imaging Telescope (EIT) on board the SOHO spacecraft has been operational since 2 January 1996 and has been used to observe the Sun over a 45 × 45 arc min field of view in four emission line groups: Fe IX, X, Fe XIIi, Fe xv, and He II.
Journal ArticleDOI
Three-dimensional Stereoscopic Analysis of Solar Active Region Loops. I. SOHO/EIT Observations at Temperatures of (1.0-1.5) × 106 K
Markus J. Aschwanden,Jeffrey Newmark,Jean-Pierre Delaboudiniere,Werner M. Neupert,James A. Klimchuk,G. Allen Gary,F. Portier-Fozzani,Arik Zucker +7 more
TL;DR: In this paper, a new method of dynamic stereoscopy is developed to reconstruct the three-dimensional geometry of dynamically changing loops, which allows us to determine the orientation of the mean loop plane with respect to the line of sight, a prerequisite to correct properly for projection effects in 3D loop models.
Journal ArticleDOI
Observations of Coronal Structures Above an Active Region by Eit and Implications for Coronal Energy Deposition
W. M. Neupert,Jeffrey S. Newmark,Jean-Pierre Delaboudiniere,Barbara J. Thompson,R. C. Catura,John D. Moses,Joseph B. Gurman,F. Portier-Fozzani,Alan H. Gabriel,G. E. Artzner,F. Clette,P. Cugnon,A. Maucherat,Jean-Marc Defise,Claude Jamar,Pierre Rochus,Kenneth P. Dere,Russell A. Howard,D. J. Michels,Samuel L. Freeland,James R. Lemen,Robert A. Stern +21 more
TL;DR: In this paper, the authors examined two relatively cool features as recorded in EIT's Fe ix/x (171 A) and Fe xii (195 A) bands in a decaying active region and found that downward thermal conductive losses (at heights above the transition region) are inadequate to support local radiative losses.
Journal ArticleDOI
Imaging the solar corona in the EUV
Jean-Pierre Delaboudiniere,Robert A. Stern,A. Maucherat,F. Portier-Fozzani,Werner M. Neupert,Joseph B. Gurman,R. C. Catura,James R. Lemen,L. Shing,G. E. Artzner,Jacqueline Brunaud,A. H. Gabriel,D. J.

TL;DR: In this article, the EIT (Extreme ultraviolet Imaging Telescope) images the Sun's corona in 4 EUV wavelengths, including the chromosphere and the base of the transition region at a temperature of 5 − 8 × 104 K.
3D-Stereoscopic Analysis of Solar Active Region Loops: I: SoHo/EIT Observations at Temperatures of 1.0-1.5 MK
Markus J. Aschwanden,Jeff Newmark,Jean-Pierre Delaboudiniere,Werner M. Neupert,F. Portier-Fozzani,G. Allen Gary,Arik Zucker +6 more
TL;DR: In this paper, the 3D geometry of dynamic changing loops is reconstructed using dynamic stereoscopy to determine the orientation of the loop plane with respect to the line-of-sight.
