length lower limit = 4 days visible in white light at limb January 8; -9; -10***; -11 (LASCO/EIT CME 1/21); -- possibly visible at West limb around December 26 Evolution comments = CIRCULAR! filament channel, eventually erupts Jan 21 West limb -- no Mk4 data that day, and channel perp to limb so cavity not visible. Note that when it is at East limb Jan 10 can see twin cavities, at top and bottom of circle Neutral line orientation at the limb = CME/dimmings association = CME erupts on West limb Jan 21 2004; prominence eruption on erupts on West limb Jan 21 2004; Active region association = N/A Filament/FC association = circular filament; N/A Other comments: N/A Filament - -- none visible Necking - no neck Cavity list (e.g. Tables 2 + 3) Full list of cavity days observed List of best cavity days (SET 1) observed (e.g. Table 1) CMEs associated with cavities (e.g. Tables 7 + 8) BACK TO TOP
