TL;DR: The Large Angle Spectroscopic Coronagraph (LASCO) is a three coronagraph package which has been jointly developed for the Solar and Heliospheric Observatory (SOHO) mission by the Naval Research Laboratory (USA), the Laboratoire d'Astronomie Spatiale (France), the Max-Planck-Institut fur Aeronomie (Germany), and the University of Birmingham (UK) as discussed by the authors.

TL;DR: The EUV Imaging Spectrometer (EIS) as mentioned in this paper is a two-element, normal incidence design with a backside-illuminated, thinned CCD, which has a significantly greater effective area than previous orbiting EUV spectrographs with typical active region 2 -5 s exposure times in the brightest lines.
Journal ArticleDOI
Measurements of Flow Speeds in the Corona Between 2 and 30 R
N. R. Sheeley,Y.-M. Wang,Scott H. Hawley,Scott H. Hawley,Guenter E. Brueckner,Kenneth P. Dere,Russell A. Howard,M. J. Koomen,Clarence M. Korendyke,D. J. Michels,S. E. Paswaters,Dennis G. Socker,O. C. St. Cyr,Dennis Wang,Philippe Lamy,A. Llebaria,Rainer Schwenn,G. M. Simnett,S. P. Plunkett,D. A. Biesecker +19 more
TL;DR: In this article, the authors tracked the birth and outflow of 50-100 of the most prominent moving coronal features and found that they originate about 3-4 R☉ from Sun center as radially elongated structures above the cusps of helmet streamers.
Journal ArticleDOI
Properties of coronal mass ejections: SOHO LASCO observations from January 1996 to June 1998
O. C. St. Cyr,Russell A. Howard,N. R. Sheeley,Simon Plunkett,D. J. Michels,S. E. Paswaters,M. J. Koomen,G. M. Simnett,Barbara J. Thompson,Joseph B. Gurman,Rainer Schwenn,David F. Webb,E. Hildner,Philippe Lamy +13 more
TL;DR: In this article, the authors report the properties of all the 841 coronal mass ejections (CMEs) observed by the SOHO Large Angle Spectroscopic Coronagraph (LASCO) C2 and C3 white-light coronagraphs from January 1996 through June 1998, and compare those properties to previous observations by other similar instruments.
