European climate response to tropical volcanic eruptions over the last half millennium [PDF]
, 2007 We analyse the winter and summer climatic signal following 15 major tropical volcanic eruptions over the last half millennium based on multi-proxy reconstructions for Europe. During the first and second post-eruption years we find significant continental

Filament eruptions and the impulsive phase of solar flares
The Astrophysical Journal, 1988 Filament motion during the onset of the solar flare impulsive phase is examined. The impulsive phase onset is established from profiles of about 30 keV X-ray fluxes and the rapid flare brightenings characteristic of the H-alpha flash phase. The filament motion begins several minutes before the impulsive or flash phase of the flare.

Small-scale motions in solar filaments as the precursors of eruptions [PDF]
Publications of the Astronomical Society of Japan, 2019 Abstract Filaments, the dense cooler plasma floating in the solar corona supported by magnetic fields, generally exhibit certain activations before they erupt. In our previous study (Seki et al. 2017, ApJ, 843, L24), we observed that the standard deviation of the line-of-sight (LOS) velocities of the small-scale motions in a filament ...

Solar filament eruptions and energetic particle events
The Astrophysical Journal, 1986 The 1981 December 5 solar filament eruption that is associated with an energetic (E greater than 50 MeV) particle event observed at 1 AU. The eruption was photographed in H-alpha and was observed by the Solwind whitelight coronagraph on P78-1. It occurred well away from any solar active region and was not associated with an impulsive microwave burst ...

Hinode Observations of the Onset Stage of a Solar Filament Eruption [PDF]
Publications of the Astronomical Society of Japan, 2007 Abstract We used Hinode X-Ray Telescope (XRT) and Solar Optical Telescope (SOT) filtergraph (FG) Stokes-V magnetogram observations, to study the early onset of a solar eruption that includes an erupting filament that we observe in TRACE EUV images.

Initiation and early kinematic evolution of solar eruptions
, 2020 We investigate the initiation and early evolution of 12 solar eruptions, including six active-region hot channel and six quiescent filament eruptions, which were well observed by the Solar Dynamics Observatory, as well as by the Solar Terrestrial ...

ERUPTION OF A SOLAR FILAMENT CONSISTING OF TWO THREADS
The Astrophysical Journal, 2012 The trigger and driving mechanism for the eruption of a filament consisting of two dark threads was studied with unprecedented high cadence and resolution of He II 304 angstrom observations made by the Atmospheric Imagining Assembly (AIA) on board the Solar Dynamics Observatory (SDO) and the observations made by the Solar Magnetic Activity Research ...

The Astrophysical Journal, 2022 Abstract Both observations and simulations suggest that the solar filament eruption is closely related to magnetic flux emergence. It is thought that the eruption is triggered by magnetic reconnection between the filament and the emerging flux. However, the details of such a reconnection are rarely presented. In this study, we report the

Journal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.ABSTRACT Microeukaryotes are important components of microbial food webs in saline and alkaline lakes, yet their diversity and distribution across distinct microhabitats remain poorly understood. We characterized microeukaryotic communities associated with microbialites, microbial mats, hypersaline waters, and sediments in the desiccating maar lake ...
