|An activated solar prominence located on
the northern equatorial eastern limb. Seeing was
intermittently good, but not sufficient to record uniform
frame cadence to produce a time lapse movie. These
11 frames were recorded between 10:10AM and 11:06AM PDT as
seeing conditions allowed. The aloft portion of the
prominence eventually lifted away while dissipating, and
fading from view. Of the two prominences at right,
the 'haystack' filament seems to be relatively stable,
while the narrow vertical filament, possibly an arching
filament foreshortened by our line of sight, displays
increasing up-flow of plasma which moves southward (to
left). Not clearly visible in these images is the
backstreaming that is occurring between an undefined point
at lower left and the activated vertical filament.
Plasma is actually moving back and forth between the
activated vertical filament and the suspended cloud to the
south. The entire prominence complex was gone shortly
after sunrise, 27 May, PDT.
