Report of the MEDOC daily meeting, 31 May 2002.

Presentation of preliminary data obtained in the MEDOC campaign

CDS preliminary data relative to the SW limb prominence observed for the
prominence atlas program, and JOP 158 (features at northern polar limb and on
the disk observed in different lines) are presented by Karin Bocchialini.

SUMER observations: JOP 158 off limb intensities of the OVI doublet, Si VIII
and Ly beta lines are presented by Eric Buchlin, and coronal line intensities
(Fe XII, N V, Mg X, Si XI) above the limb, observed at the North pole, are
compared to the South pole and quiet sun data by Laurent Dolla.
