A TYPE II RADIO BURST WITHOUT A CORONAL MASS EJECTION [PDF]

open access: yes, 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.

Effect of an Interplanetary Coronal Mass Ejection on Saturn’s Radio Emission

open access: yesFrontiers 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 ...

Solar Physics with the Square Kilometre Array [PDF]

open access: yes, 2018
The Square Kilometre Array (SKA) will be the largest radio telescope ever built, aiming to provide collecting area larger than 1 km$^2$. The SKA will have two independent instruments, SKA-LOW comprising of dipoles organized as aperture arrays in ...

A SOLAR CORONAL JET EVENT TRIGGERS A CORONAL MASS EJECTION [PDF]

open access: yes, 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 ...

WHY DOES THE APPARENT MASS OF A CORONAL MASS EJECTION INCREASE? [PDF]

open access: yes, 2015
Mass is one of the most fundamental parameters characterizing the dynamics of a coronal mass ejection (CME). It has been found that CME apparent mass measured from the brightness enhancement in coronagraphs increases during its evolution in the corona ...

THE ROLE OF ACTIVE REGION CORONAL MAGNETIC FIELD IN DETERMINING CORONAL MASS EJECTION PROPAGATION DIRECTION [PDF]

open access: yes, 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).

Unusual shrinkage and reshaping of Earth’s magnetosphere under a strong northward interplanetary magnetic field

open access: yesCommunications Earth & Environment, 2023
Open magnetic flux in the polar cap almost completely disappeared and the Earth’s magnetotail was compressed into a calabash shape during the 9th April 2015 coronal mass ejection, according to magnetohydrodynamic simulations and observations from DMSP ...

Coronal Mass Ejections and Coronal Structures [PDF]

open access: yes, 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.

Periodicities in solar coronal mass ejections [PDF]

open access: yesMonthly 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).

PHYSICAL CONDITIONS OF CORONAL PLASMA AT THE TRANSIT OF A SHOCK DRIVEN BY A CORONAL MASS EJECTION [PDF]

open access: yes, 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).
