CORONAL MASS EJECTIONS AND SUNSPOTS—SOLAR CYCLE PERSPECTIVE

open access: yesThe Astrophysical Journal, 2010
Recent studies have indicated that the occurrence of the maxima of coronal mass ejection (CME) rate and sunspot number (SSN) were nearly two years apart. We find that the two-year lag of CME rate manifests only when the SSN index is considered and the lag is minimal (two-three months) when the sunspot area is considered.

Transport in the interplanetary medium of coronal mass ejections [PDF]

open access: yesGeofísica Internacional, 2008
Coronal mass ejections (CMEs) are large scale structures of plasma and magnetic field expelled from the Sun to the interplanetary medium and generally observed in white light coronagraphs.

3D Non-equilibrium Ionization and Spectroscopic Modeling of Coronal Mass Ejections. II. CME Energy Budget

open access: yesThe Astrophysical Journal
Coronal mass ejections (CMEs) release between ≈10 ^30 and 10 ^33 erg of energy into the corona; however, their detailed energy budget is difficult to constrain.

Discrepancies in the Properties of a Coronal Mass Ejection on Scales of 0.03 au as Revealed by Simultaneous Measurements at Solar Orbiter and Wind: The 2021 November 3–5 Event

open access: yesThe Astrophysical Journal
Simultaneous in situ measurements of coronal mass ejections (CMEs), including both plasma and magnetic field, by two spacecraft in radial alignment have been extremely rare.

Comparative Analysis of Properties of Coronal Mass Ejections at High and Low Apparent Latitudes in 1996–2025

open access: yesThe Astrophysical Journal
This study examines the statistical properties of coronal mass ejections (CMEs) over two and a half solar cycles (1996–2025) using coronal observations from the SOHO LASCO CDAW and CACTus catalogs, supplemented by sunspot number records and in situ ...

Characterizing Coronal Mass Ejections in Solar Cycle Analysis

open access: yes, 2018
The Sun is the major source of heat and light in our solar system. The solar cycle is the 11-year cycle of solar activity that can be determined by the rise and fall in the numbers and surface area of sunspots. Solar activity is associated with several factors including radio flux, solar irradiance, magnetic field, solar flares, coronal mass ejections,
