length lower limit = 2 days visible in white light at limb November 18; -19 (CME!);

Recurrence =West limb September 18; -19; East limb October 1**; West limb October 19**; East limb November 2**; West limb November 18; -19 (CME!); West limb December 13; Also visible Feb-Apr 2000
Evolution comments = PCF-S -- 8 month supersystem. No LASCO CME movies Oct 1-5 -- but fil visible in 304 for several days so probably doesnt erupt then. No Mk4 data Oct 20-23, but no LASCO CME in the right place then. Likewise, no Mk4 dat Nov 3-7, but no LASCO CME. Cavity visible Nov 18 (no data Nov 17) and blows in a ***MK4 CME*** on Nov 19! No Mk4 Dec 1-6... Cavity visible Dec 13, then not clear soon thereafter -- no CME in LASCO, no EIT images to compare to. Dec 27 the PCF-S is not visible, but a higher, angled CF with nice bulbous cavity is that erupts (see next system). PCF-S becomes clear again in H-alpha, and eventually part of this PCF-S shows cavity Feb - Apr 2000.

Neutral line orientation at the limb =
CME/dimmings association = CME Nov 19;
Active region association = N/A

Filament/FC association = PCF-S -- note lower of two CF; PCF-S - note lower of 2 CF
Other comments: N/A
Filament - -- none visible

Necking - no neck
