Ground-Based Coronagraphic Observations of Solar Streamers. (Reannouncement withNew Availability Information)

摘要

The purpose of this paper is two-fold: first, to demonstrate that ground-basedcoronagraphs can observe coronal streamers and, secondly, to give examples of the type of streamer properties that can be deduced from such observations. This paper will not discuss eclipse or balloon-borne observations. The former will be discussed by another paper in this volume, and the latter are more properly discussed with respect to space-borne observations. Here, emission-line and white-light (K-coronagraph) observations relating to streamer electron density, magnetic field and polarization, population, intensity, large-scale organization, rotation, temperature and periodicities are included. This paper will not be an exhaustive review of all known papers in this field but will only use selected papers to demonstrate the types of work that can be done....
