Modeling Polarized Radio Sounding Observations of a Coronal Mass Ejection

The Astrophysical Journal
Coronal mass ejections (CMEs) evolve significantly as they propagate from the Sun to the Earth, so remote observations of their changes in speed, strength of the magnetic field, density, and overall structure are critical for predicting their arrival ...

A Challenging Solar Eruptive Event of 18 November 2003 and the Causes of the 20 November Geomagnetic Superstorm. I. Unusual History of an Eruptive Filament

, 2013
This is the first of four companion papers, which analyze a complex eruptive event of 18 November 2003 in AR 10501 and the causes of the largest Solar Cycle 23 geomagnetic storm on 20 November 2003. Analysis of a complete data set, not considered before,

Coronal "Wave": Magnetic Footprint of a Coronal Mass Ejection?

The Astrophysical Journal, 2007
We investigate the properties of two "classical" EUV Imaging Telescope (EIT) coronal waves. The two source regions of the associated coronal mass ejections (CMEs) possess opposite helicities, and the coronal waves display rotations in opposite senses.

On the Optimal Prediction of Extreme Events in Heavy‐Tailed Time Series With Applications to Solar Flare Forecasting

Journal of Time Series Analysis, Volume 47, Issue 1, Page 25-42, January 2026.
ABSTRACT The prediction of extreme events in time series is a fundamental problem arising in many financial, scientific, engineering, and other applications. We begin by establishing a general Neyman–Pearson‐type characterization of optimal extreme event predictors in terms of density ratios.

Identifying Coronal Mass Ejection Active Region Sources: An Automated Approach

The Astrophysical Journal
Identifying the source regions of coronal mass ejections (CMEs) is crucial for understanding their origins and improving space weather forecasting. We present an automated algorithm for matching CMEs detected by the Large Angle Spectrometric Coronagraph ...

Tracking Streamer Blobs Into the Heliosphere

, 2010
In this paper, we use coronal and heliospheric images from the STEREO spacecraft to track streamer blobs into the heliosphere and to observe them being swept up and compressed by the fast wind from low-latitude coronal holes.

Upwelling Metallic Ions Producing Valley Region Irregularities Over Low Latitude During the 2025 New Year Magnetic Storm

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Valley region irregularities (VRIs) have been previously investigated using radar, ionosonde, and rocket‐borne in situ observations. In this paper, based on a joint observational experiment by lidar and radars performed in Hainan, China, we report a case of low‐latitude VRIs generated in association with uplifted metallic ions for the first ...
