Center =22.98+/-1.17 degrees PA (NE quadrant) (red radial line)	Maximum height = 1.47+/-0.04 Rsun
Width (at 1.20 Rsun) = 18.42+/-0.96 degrees latitude (measured between edges -- vertical dashed lines at inflection points)	Width (at 1.33 Rsun) = 17.10+/-1.39 degrees latitude
Cavity depletion, equatorward (1.20 Rsun) = 0.16+/-0.021 (ratio of red to blue dashed line)	Cavity depletion, equatorward (at 1.33 Rsun) = 0.05+/-0.019 (ratio of red to blue dashed line)
Cavity depletion, poleward (1.20 Rsun) = 0.15+/-0.027 (ratio of green to blue dashed line) Minimum intensity in cavity (1.20 Rsun) = 2.4e-07+/-3.5e-09 (Bsun) (blue dashed lines);	Cavity depletion, poleward (1.33 Rsun) = 0.09+/-0.018 (ratio of green to blue dashed line) Minimum intensity in cavity (1.33 Rsun) = 1.6e-07+/-1.6e-09 (Bsun) (blue dashed lines);
Slope at equatorward cavity edge (1.20 Rsun) = 1.1e-08+/-4.8e-09 (Bsun/degree)	Slope at equatorward cavity edge (1.33 Rsun) = 4.9e-09+/-3.2e-09 (Bsun/degree)
Slope at poleward cavity edge (1.20 Rsun) = -1.2e-08+/-4.8e-09 (Bsun/degree)	Slope at poleward cavity edge (1.33 Rsun) = 8.6e-10+/-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; N/A
Other comments: cavity faintly visible in EUV
Filament - visible in white light
Necking - straight up and down neck
