Evolution comments = Again only a small piece of filament visible in H-alpha, but quite high polar cavity visible recurrently for 2-3 months at least. Originally visible Dec 31, then Jan 6-9 West limb, then around Jan 23 East limb (not shown), then West limb Feb 23-24, poss 25, poss a little 26, although obscured. LASCO EIT out Feb 25-26. Possibly affected by filament erupt/CME Feb 28, although this mainly affects long, kinked CF closer to equator. Cavity shows up again nicely at West limb on March 4-5-6-7-8...
