Abstract
Aims.Coronal plumes, along with their structure and rôle in the
acceleration of the fast solar wind, are of considerable importance in
understanding the physics of the solar atmosphere, in particular, when contrasted
with the adjacent plasma, the so-called interplume regions.
Methods.Observations of coronal plumes in a coronal hole were obtained
with the help of spectrographs and imagers on Hinode,
SOHO, STEREO, TRACE, and with ground-based instrumentation.
The measurements were performed by a large international team in April 2007.
Results.First results of this study from Hinode, SOHO, and STEREO
are presented here, at the level of observational facts,
leaving the task of detailed analysis to the future.
