Center =126.27+/-1.00 degrees PA (SE quadrant) (red radial line)
Maximum height = 1.37+/-0.04 Rsun
Width (at 1.20 Rsun) = 9.06+/-0.77 degrees latitude (measured between edges -- vertical dashed lines at inflection points)
Width (at 1.28 Rsun) = 7.48+/-1.24 degrees latitude
Cavity depletion, equatorward (1.20 Rsun) = 0.58+/-0.018 (ratio of red to blue dashed line)
Cavity depletion, equatorward (at 1.28 Rsun) = 0.53+/-0.012 (ratio of red to blue dashed line)
Cavity depletion, poleward (1.20 Rsun) = 0.02+/-0.051 (ratio of green to blue dashed line) Minimum intensity in cavity (1.20 Rsun) = 1.5e-07+/-4.8e-09 (Bsun) (blue dashed lines);
Cavity depletion, poleward (1.28 Rsun) = 0.05+/-0.032 (ratio of green to blue dashed line) Minimum intensity in cavity (1.28 Rsun) = 1.1e-07+/-1.7e-09 (Bsun) (blue dashed lines);
Slope at equatorward cavity edge (1.20 Rsun) = -2.2e-08+/-3.0e-09 (Bsun/degree)
Slope at equatorward cavity edge (1.28 Rsun) = -1.3e-08+/-2.2e-09 (Bsun/degree)
Slope at poleward cavity edge (1.20 Rsun) = 5.3e-09+/-3.0e-09 (Bsun/degree)
Slope at poleward cavity edge (1.28 Rsun) = 2.2e-09+/-2.2e-09 (Bsun/degree)

length lower limit = 2 days visible in white light at limb August 8****; -9 (CME!);

No Recurrence analyzed
Evolution comments = CME case - another small one

Neutral line orientation at the limb =
CME/dimmings association = CME August 9; prominence eruption on August 9;

Active region association = N/A

Filament/FC association = high prominence at limb; N/A

Other comments: N/A

Filament - only visible in H-alpha or EUV

Necking - straight up and down neck
