 abstract of observational proposal
EIS has observed twist in filaments before eruption, and several filaments during eruption with long rasters. The purpose of this HOP is to observe the change in flows in the build-up to and during the eruption of a filament. This requires a fast raster over a filament on disk. It will be a target of opportunity.  Make use of STEREO behind data to identify a target.  To be run for a period of a day at a time or for periods of 4 to 12 hours on consecutive days.

 request to SOT
Ca II , FG magnetograms with occasional fast SP maps (~one per hour?).

 request to XRT
Concentrate on dynamics with thinner filters.

 request to EIS
There are three EIS studies available: two for quiescent filaments, one narrow and one extended. One for an active region filament,

Narrow Quiescent study: Quiet_fil_narrow, ID # 383, Lines: He II (256.32), Fe VIII (185.21), Fe XII (195.12), 2hslit, sparse raster with 10hsteps and 60 sec exposure, FoV is 102" width by 200hheight, raster duration: 12m 17s, data volume: 0.5 Mbit, compression: JPEG95
Point at a short QS filament. Repeat raster to take continuous data at same pointing. Hinode to track filament.

Wide Quiescent study: Quiet_fil_wide, ID #384, Lines: He II (256.32), Fe VIII (185.21), Fe XII (195.12), 2hslit, sparse raster with 20hsteps and 60 sec exposure, FoV is 202h width by 200h height, raster duration: 12m 17s, data volume: 0.5 Mbit, compression: JPEG95.
Centre study on mid-filament where eruption most likely. Repeat raster to take continuous data at same pointing. Hinode to track filament.

Active Region filament study: AR_filament,ID #385, Lines: He II (256.32), Fe VIII (185.21), Fe XII (195.12), Si VII (275.35), Fe XXIV (192.02), 2hslit, sparse raster with 10hsteps and 10 s exposure, FoV is 242h width by 200" height, raster duration: 5m 11s, data volume: 2.0 Mbit, compression: JPEG95.
Point at AR filament. Repeat raster to take continuous data at same pointing. Hinode to track filament.
AR filament study designed to monitor changes in flows prior to eruption.

For long or complex filaments, consult proposal contacts for pointing specification.

 remarks
If studies run as part of HOP 150, do not lower the compression quality below JPEG95
The authors will alert the team to a suitable filament.
