Micro-Sigmoids as Progenitors of Coronal Jets - Is Eruptive Activity Self-Similarly Multi-Scaled?

, 2010
Observations from the X-ray telescope (XRT) on Hinode are used to study the nature of X-ray bright points, sources of coronal jets. Several jet events in the coronal holes are found to erupt from small-scale, S-shaped bright regions.

Characteristics of Magnetic Clouds and Interplanetary Coronal Mass Ejections which Cause Intense Geomagnetic Storms

Terrestrial, Atmospheric and Oceanic Sciences, 2013
We present the results of a statistical data analysis of the geo-effectiveness of non-magnetic-cloud interplanetary coronal mass ejections (ICMEs) and compare them with those of magnetic-cloud (MC) interplanetary coronal mass ejections observed during ...

Role of coronal mass ejections in the heliospheric Hale cycle [PDF]

, 2007
[1] The 11-year solar cycle variation in the heliospheric magnetic field strength can be explained by the temporary buildup of closed flux released by coronal mass ejections (CMEs).

Effects of Coronal Mass Ejections on Distant Coronal Streamers

, 2014
The effects of a large coronal mass ejection (CME) on a solar coronal streamer located roughly 90 degrees from the main direction of the CME propagation observed on January 2, 2012 by the SOHO/LASCO coronagraph are analyzed.

Large-scale Coronal Dimming Foreshadowing a Solar Eruption on 2011 October 1

The Astrophysical Journal
Understanding large-scale solar eruptions requires detailed investigation of the entire system’s evolution, including the magnetic environment enveloping the source region and searches for precursor activity prior to event onset.

CME dynamics using STEREO & LASCO observations: the relative importance of Lorentz forces and solar wind drag

, 2017
We seek to quantify the relative contributions of Lorentz forces and aerodynamic drag on the propagation of solar coronal mass ejections (CMEs). We use Graduated Cylindrical Shell (GCS) model fits to a representative set of 38 CMEs observed with the SOHO
