length lower limit = 2 days visible in white light at limb March 2; -3 (CME!);
Recurrence =East limb February 3; -4; -5 (CME!); East limb March 2; -3 (CME!); West limb March 15**; East limb March 30** ; West limb April 13**; Also visible Sep-Dec 1999
Evolution comments = PCF-S -- same as Sept-Dec 99, but cavity over different portion. Visible both limbs at times. Also visible March 14,16... West limb -- many other days. Possible eruption April 15 -- but no Mk4 data -- and may be too far from pole. System probably exist longer than shown here. At least two Mk4 eruptions, Feb 5 and Mar 3 (orig CME cases).

Neutral line orientation at the limb =
CME/dimmings association = CME March 3 (also Feb 5); prominence eruption on March 3;
Active region association = N/A
Filament/FC association = PCF-S; polar crown filament
Other comments: N/A
Filament - visible in white light
Necking - bulging neck
