This two-part book is devoted to classic fundamentals and current practices and
perspectives of modern plasma astrophysics. This second part discusses the physics of …

We apply statistical tests based on discriminant analysis to the wide range of photospheric
magnetic parameters described in a companion paper by Leka & Barnes, with the goal of …

Photospheric vector magnetic field data from the University of Hawai'i Imaging Vector
Magnetograph, with good spatial and temporal sampling, are used to study the question of …

A large fraction of major flares occur in active regions that exhibit a δ configuration. The
formation and disintegration of δ configurations is very important in understanding the …

At the request of the conference attendees, we have compiled a classification of extended
radio sources in clusters. These range from scales of tens of parsecs to over a megaparsec …

We studied the behavior of magnetic field, horizontal motion and helicity in a fast emerging
flux region NOAA 10488 which eventually forms a δ spot. It is found that the rotation of …

As compared with the Mount Wilson Magnetic Classification (MWMC), effective distance (d
E) is a useful parameter because it gives a quantitative measure of magnetic configuration in …

Abstract We revisit the Bastille Day flare/CME Event of 2000 July 14, and demonstrate that
this flare/CME event is not related to only one single active region (AR). Activation and …

We present new observations of the interactions of two close, but distinct, Hα filaments and
their successive eruptions on 5 November 1998. The magnetic fields of the filaments are …

The purpose of this paper is to show that large active regions (ARs) with different magnetic
configurations have different contributions to short-term and long-term variations of the Sun …
