We propose to follow the morphology of the filemants observed by EIT
during the support of JOP029 - Filament Flows to support the
corrseponding observations made by CDS, SUMER and the Swedish Solar
Tower at LaPalma.

The source of mass for quiescent filaments is still an open
question. According to current thinking, the mass is injected from the
chromosphere, possibly along the long appendages ("feet" or "barbs")
rather than by condensation of coronal matter. Indeed, recent
observations by S. Martin and O. Engvold based on high-resolution
H-alpha filtergrams, supports this view. The coordinated onservations
made during JOP029 should give us new information about what supports
the filament structures.

The data we ask permission to use is the observations obtained between
12:00 - 15:30 UT everyday from September 17 to September 30. EIT
observed high and low cadense sub-fields of the filaments as well as a
few full disk images. We will also ask to use full disk images in all
four filters taken just prior or after the allocated JOP time slot.
The latter is usefil for accurate co-alignment between the different
obervations.


We will work with Joe Gurman.
