Activated Solar Prominence, Eastern Equatorial Limb
26 May 2016

Jim Ferreira, Livermore CA   bakerst@comcast.net

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.
