TL;DR: In this article, the authors report on the state-of-the-art in algorithms used for resolving the 180° ambiguity in solar vector magnetic field measurements and compare them quantitatively and seek to understand where each succeeds, where it fails and why.

TL;DR: In this article, the authors present the "Drag-Based Model" (DBM) of heliospheric propagation of interplanetary coronal mass ejections (ICMEs) based on the hypothesis that the driving Lorentz force, which launches a CME, ceases in the upper corona and that beyond a certain distance the dynamics becomes governed by the interaction of the ICME and the ambient solar wind.

TL;DR: In this article, the fine temporal and spatial structure of a filament eruption on 2002 May 27 following an M2-class flare was observed at the Big Bear Solar Observatory, with a cadence of 40 ms. The event appears to be a failed eruption, as the filament material, seen in absorption by TRACE, first accelerated then decelerated as it approached its peak height of similar to 8 x 10(4) km while the filament threads drained back to the Sun.

TL;DR: In this paper, a comprehensive statistical study is performed to address the question of whether two classes of coronal mass ejections (CMEs) exist, and the correlation between speed and acceleration of CMEs is investigated.

TL;DR: The Big Bear Solar Observatory Active Region Monitor (ARM) as discussed by the authors uses full-disk Hα images from the Global Hα Network; EUV, continuum and magnetogram data from the Solar and Heliospheric Observatory (SOHO); and fulldisk magnetograms from the global Oscillation Network Group (GONG).
