Progress
Draft Scheme: January 15 1996
Discussion at SPWG: February 9 1996
Detailed Plan: February 21 1996
Distributed to PI Teams: February 21 1996
Refinements: April 16 1996

Objective
To study the structure and evolution of coronal holes, with special emphasis on the structure and activities in the boundaries.

Conditions Necessary to Run
Identification of a well defined coronal hole and involvement, at a minimum, of CDS and EIT.

Scientific Case
This JOP is designed to study the structure and development of coronal holes. In particular the process that occur in the boundary region are examined. The JOP is supported by the on-going CDS synoptic scans and two dedicated Studies (BOUND and CHSTR). These are complementary to the SUMER POP 21. The target coronal hole is mapped and a boundary region is chosen for special attention. Supporting data from the more "global" views afforded by LASCO, EIT and Yohkoh are sought.

Pointing and Target Selection
Coronal hole, preferably with well defined boundary, with minimum line of sight contamination from overlying structures.
