Center =330.04+/-0.68 degrees PA (NW quadrant) (red radial line)	Maximum height = 1.60+/-0.03 Rsun
Width (at 1.20 Rsun) = 23.42+/-0.59 degrees latitude (measured between edges -- vertical dashed lines at inflection points)	Width (at 1.40 Rsun) = 17.62+/-0.77 degrees latitude
Cavity depletion, equatorward (1.20 Rsun) = 0.22+/-0.016 (ratio of red to blue dashed line)	Cavity depletion, equatorward (at 1.40 Rsun) = 0.11+/-0.018 (ratio of red to blue dashed line)
Cavity depletion, poleward (1.20 Rsun) = 0.01+/-0.020 (ratio of green to blue dashed line) Minimum intensity in cavity (1.20 Rsun) = 2.4e-07+/-2.4e-09 (Bsun) (blue dashed lines);	Cavity depletion, poleward (1.40 Rsun) = 0.02+/-0.020 (ratio of green to blue dashed line) Minimum intensity in cavity (1.40 Rsun) = 1.1e-07+/-1.1e-09 (Bsun) (blue dashed lines);
Slope at equatorward cavity edge (1.20 Rsun) = -8.8e-09+/-4.9e-09 (Bsun/degree)	Slope at equatorward cavity edge (1.40 Rsun) = -2.1e-09+/-2.1e-09 (Bsun/degree)
Slope at poleward cavity edge (1.20 Rsun) = 2.0e-09+/-4.9e-09 (Bsun/degree)	Slope at poleward cavity edge (1.40 Rsun) = 5.6e-10+/-2.1e-09 (Bsun/degree)

length lower limit = 2 days visible in white light at limb December 29***; -30;
No Recurrence analyzed
Evolution comments = Also visible 28 Dec. Not really visible 31 Dec. No eruption apparent LASCO or EIT, however filament appears to be more perpendicular to limb by 31 Dec. Possible backside CME LASCO 1/2/02

Neutral line orientation at the limb =
CME/dimmings association = N/A
Active region association = N/A
Filament/FC association = Filament becoming parallel to limb by Dec 31; N/A
Other comments: N/A
Filament - only visible in H-alpha or EUV
Necking - bulging neck
