Evolution comments = Angled CF-S -- originally mistaken for part of Sept - Dec 99 cavity system, but turns out higher latitude, related to different filament channel. Nice and bulbous cavity Dec 26. Bad Mk4 data Dec 27, poss visible 28, gone 29 -- and indeed, the PCF appears to erupt in EIT and LASCO on Dec 29. Too early for Mk4, unfortunately. |
