A TYPE II RADIO BURST WITHOUT A CORONAL MASS EJECTION [PDF]
, 2015 Type II radio bursts are thought to be a signature of coronal shocks. In this paper, we analyze a short-lived type II burst that started at 07:40 UT on 2011 February 28.

Deriving the radial distances of wide coronal mass ejections from elongation measurements in the heliosphere - Application to CME-CME interaction [PDF]
, 2009 We present general considerations regarding the derivation of the radial distances of coronal mass ejections (CMEs) from elongation angle measurements such as those provided by SECCHI and SMEI, focusing on measurements in the Heliospheric Imager 2 (HI-2)

A SOLAR CORONAL JET EVENT TRIGGERS A CORONAL MASS EJECTION [PDF]
, 2015 In this paper, we present multi-point, multi-wavelength observations and analysis of a solar coronal jet and coronal mass ejection (CME) event. Employing the GCS model, we obtained the real (three-dimensional) heliocentric distance and direction of the ...

PHYSICAL CONDITIONS OF CORONAL PLASMA AT THE TRANSIT OF A SHOCK DRIVEN BY A CORONAL MASS EJECTION [PDF]
, 2015 We report here on the determination of plasma physical parameters across a shock driven by a coronal mass ejection using white light (WL) coronagraphic images and radio dynamic spectra (RDS).

Observations of Coronal Mass Ejections with the Coronal Multichannel Polarimeter [PDF]
Solar Physics, 2013 The Coronal Multichannel Polarimeter (CoMP) measures not only the polarization of coronal emission, but also the full radiance profiles of coronal emission lines. For the first time, CoMP observations provide high-cadence image sequences of the coronal line intensity, Doppler shift and line width simultaneously in a large field of view. By studying the

THE ROLE OF ACTIVE REGION CORONAL MAGNETIC FIELD IN DETERMINING CORONAL MASS EJECTION PROPAGATION DIRECTION [PDF]
, 2015 We study the role of the coronal magnetic field configuration of an active region (AR) in determining the propagation direction of a coronal mass ejection (CME).

A slow coronal mass ejection with rising X-ray source [PDF]
, 2005 An eruptive event, which occurred on 16th April 2002, is discussed. Using images from the Transition Region and Coronal Explorer ( TRACE) at 195 angstrom, we observe a lifting flux rope which gives rise to a slow coronal mass ejection ( CME).

Coronal Mass Ejections and Coronal Structures [PDF]
, 1989 The coronal portion of the solar atmosphere consists of a wide variety of structures which exhibit a similarly wide variety of dynamical processes and kinds of activity. The launch of the SMM presented an opportunity to study the low and intermediate corona from space with multiple instruments for protracted periods of time.

The relationship of coronal mass ejections to streamers [PDF]
Journal of Geophysical Research: Space Physics, 1999 We have examined images from the Large‐Angle and Spectrometric Coronagraph (LASCO) to study the relationship of coronal mass ejections (CMEs) to coronal streamers. We wish to test the suggestion [Low, 1996] that CMEs arise from flux ropes embedded in a streamer erupting and disrupting the streamer. The data span a period of 2 years near Sunspot minimum

Deflected propagation of a coronal mass ejection from the corona to interplanetary space [PDF]
, 2014 Among various factors affecting the space weather effects of a coronal mass ejection (CME), its propagation trajectory in the interplanetary space is an important one determining whether and when the CME will hit the Earth.
