Continuous observations were performed of a quiescent prominence with the Solar Optical Telescope on board the Hinode satellite on 2006 December 23 and 24. A peculiar slowly rising column of {approx}10{sup 4} K plasma develops from the lower atmosphere during the observations. The apparent ascent speed of the column is 2 km s{sup -1}, while the fine structures of the column exhibit much faster motion of up to 20 km s{sup -1}. The column eventually becomes a faint low-lying prominence. An…

Description and Classification of Prominences
Solar prominences are bright cloud-like structures when observed beyond the solar limb and they appear as dark filamentary objects which are termed filaments when seen against the solar disk. The
Magneto-thermal convection in solar prominences
TLDR
Optical and extreme-ultraviolet observations of polar crown prominences show that these bubbles contain plasma at temperatures in the range (2.5–12) × 105 kelvin, which is 25–120 times hotter than the overlying prominence, and suggests that the coronal cavity–prominence system supports a novel form of magneto-thermal convection in the solar atmosphere.
THE MAGNETIC STRUCTURE OF SOLAR PROMINENCE CAVITIES: NEW OBSERVATIONAL SIGNATURE REVEALED BY CORONAL MAGNETOMETRY
The Coronal Multi-Channel Polarimeter (CoMP) obtains daily full-Sun above-the-limb coronal observations in linear polarization, allowing, for the first time, a diagnostic of the coronal magnetic
Multiwavelength Observations of a Failed Flux Rope in the Eruption and Associated M-Class Flare from NOAA AR 11045
We present the multiwavelength observations of a flux rope that was trying to erupt from NOAA AR 11045 and the associated M-class solar flare on 12 February 2010 using space-based and ground-based
Impact of Dynamic State on the Mass Condensation Rate of Solar Prominences
The interiors of quiescent prominences are filled with turbulent flows. The evolution of upflow plumes, descending pillars, and vortex motions has been clearly detected in high-resolution
THE RAPID FORMATION OF A FILAMENT CAUSED BY MAGNETIC RECONNECTION BETWEEN TWO SETS OF DARK THREADLIKE STRUCTURES
Taking advantage of the high spatiotemporal resolution observations from the Atmospheric Imaging Assembly (AIA) and the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory, we
Quiescent prominence dynamics observed with the Hinode Solar Optical Telescope . II. Prominence Bubble Boundary Layer Characteristics and the Onset of a Coupled Kelvin-Helmholtz Rayleigh-Taylor Instability
We analyze solar quiescent prominence bubble characteristics and instability dynamics using Hinode/Solar Optical Telescope (SOT) data. We measure bubble expansion rate, prominence downflows, and the
Filaments and Prominences
Filaments (when seen in absorption on the solar disk) or prominences (when seen in emission above the limb) reveal the location of the magnetic neutral line in active regions and often represent
The magnetic Rayleigh–Taylor instability in solar prominences
The magnetic Rayleigh–Taylor instability is a fundamental instability of many astrophysical systems, and recent observations are consistent with this instability developing in solar prominences.
Reconnection-Condensation Model for Solar Prominence Formation
We propose a reconnection-condensation model in which topological change in a coronal magnetic field via reconnection triggers radiative condensation, thereby resulting in prominence formation.

Prominence Formation Associated with an Emerging Helical Flux Rope
The formation and evolution process and magnetic configuration of solar prominences remain unclear. In order to study the formation process of prominences, we examine continuous observations of a

Quiescent prominences occur as long-lasting cool sheets of matter in the surrounding hot corona at the base of coronal streamers. Seen on the disk they appear as dark filaments dividing regions of
