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.

Deciphering the Slow-rise Precursor of a Major Coronal Mass Ejection
The Astrophysical Journal Letters, 2023 Coronal mass ejections are explosive plasma phenomena prevalently occurring on the Sun and probably on other magnetically active stars. However, how their pre-eruptive configuration evolves toward the main explosion remains elusive.

Effect of an Interplanetary Coronal Mass Ejection on Saturn’s Radio Emission
Frontiers in Astronomy and Space Sciences, 2022 The Saturn Kilometric Radiation (SKR) was observed for the first time during the flyby of Saturn by the Voyager spacecraft in 1980. These radio emissions, in the range of a few kHz to 1 MHz, are emitted by electrons travelling around auroral magnetic ...

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).

Initiation of Coronal Mass Ejections by Sunspot Rotation [PDF]
Solar Physics, 2013 AbstractWe report observations of a filament eruption, two-ribbon flare, and coronal mass ejection (CME) that occurred in Active Region NOAA 10898 on 6 July 2006. The filament was located South of a strong sunspot that dominated the region. In the evolution leading up to the eruption, and for some time after it, a counter-clockwise rotation of the ...

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).

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 ...

Periodicities in solar coronal mass ejections [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 Mid-term quasi-periodicities in solar coronal mass ejections (CMEs) during the most recent solar maximum cycle 23 are reported here for the first time using the four-year data (February 5, 1999 to February 10, 2003) of the Large Angle Spectrometric Coronagraph (LASCO) onboard the Solar and Heliospheric Observatory (SOHO).

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).

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
