Center =26.22+/-0.51 degrees PA (NE quadrant) (red radial line)
Maximum height = 1.36+/-0.02 Rsun
Width (at 1.20 Rsun) = 10.66+/-0.45 degrees latitude (measured between edges -- vertical dashed lines at inflection points)
Width (at 1.28 Rsun) = 9.37+/-0.57 degrees latitude
Cavity depletion, equatorward (1.20 Rsun) = 0.28+/-0.014 (ratio of red to blue dashed line)
Cavity depletion, equatorward (at 1.28 Rsun) = 0.15+/-0.019 (ratio of red to blue dashed line)
Cavity depletion, poleward (1.20 Rsun) = 0.18+/-0.016 (ratio of green to blue dashed line) Minimum intensity in cavity (1.20 Rsun) = 2.2e-07+/-2.2e-09 (Bsun) (blue dashed lines);
Cavity depletion, poleward (1.28 Rsun) = 0.15+/-0.018 (ratio of green to blue dashed line) Minimum intensity in cavity (1.28 Rsun) = 1.6e-07+/-1.6e-09 (Bsun) (blue dashed lines);
Slope at equatorward cavity edge (1.20 Rsun) = 1.6e-08+/-4.4e-09 (Bsun/degree)
Slope at equatorward cavity edge (1.28 Rsun) = 1.1e-08+/-3.2e-09 (Bsun/degree)
Slope at poleward cavity edge (1.20 Rsun) = -2.0e-08+/-4.4e-09 (Bsun/degree)
Slope at poleward cavity edge (1.28 Rsun) = -4.7e-09+/-3.2e-09 (Bsun/degree)

length lower limit = 2 days visible in white light at limb November 2; -3*** (LASCO/EIT CME (11));

No Recurrence analyzed
Evolution comments = PCF-N (curved). Mk4 data dropout Nov 4-8. EIT 304 implies filament still there for some time - possible eruption Nov 11 -- EIT sees filament erupt, LASCO sees CME, right place and time. Not apparent Nov 17, then Mk4 data dropout for several days.

Neutral line orientation at the limb =
CME/dimmings association = November 11;

Active region association = N/A

Filament/FC association = prominence at limb; filament channel

Other comments: cavity faintly visible in EUV

Filament - visible in white light

Necking - straight up and down neck
