| 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). |
