Observational Evidence of Solar Spicules Associated with Microfilament Eruptions Using DKIST

The Astrophysical Journal Letters
The formation mechanism of spicules is fundamentally important for understanding mass and energy transport from the chromosphere into the corona. Recent studies suggested that spicules may be powered by microfilament eruptions.

Source Region and Launch Characteristics of Magnetic-arch-blowout Solar Coronal Mass Ejections Driven by Homologous Compact-flare Blowout Jets

The Astrophysical Journal
We study the formation of four coronal mass ejections (CMEs) originating from homologous blowout jets. All of the blowout jets originated from NOAA Active Region (AR) 11515 on 2012 July 2, within a time interval of ≈14 hr.

Two-stage Primary Acceleration in Filament Initial Eruption under a Fan–Spine Magnetic Configuration

The Astrophysical Journal
Understanding the filament rising process is crucial for unveiling the triggering mechanisms of coronal mass ejections and forecasting space weather. In this paper, we present a detailed study of the filament initial eruption under a fan–spine structure.

Chromospheric Magnetic Field Extrapolations Reveal the Flux-rope Configuration of a Solar Filament

The Astrophysical Journal Letters
Solar eruptions are powered by the release of magnetic energy stored in the lower solar atmosphere, but the preeruptive magnetic configuration of filament channels remains difficult to determine.

Filament Eruptions, Jets, and Space Weather [PDF]

, 2013
Previously, from chromospheric H alpha and coronal Xray movies of the Sun's polar coronal holes, it was found that nearly all coronal jets (greater than 90%) are one or the other of two roughly equally common different kinds, different in how they erupt:

Research into the Magnetic Configuration of Eruptive Filaments with a High-class Flare

The Astrophysical Journal
Filament eruptions are the source of coronal mass ejections, and these phenomena are likely to pose a serious threat to space weather safety. The magnetic structures that carry the filament material are considered the core structures of the eruption, and

Observation of sulphate aerosols and SO2 from volcanic eruptions using data from the Atmospheric Chemistry Experiment (ACE) [PDF]

, 2011
Infrared spectra measured by the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) on board of the SCISAT satellite were used to analyse the temporal and spatial evolution of volcanic aerosols from the Kasatochi (August 2008 ...
