Details:
On November 11th, a prominence lifted off the sun at the same time as a filament lifted off. I did not see any connection (pretty far apart), but it is quite a coincidence. Also a coincidence.....I happened to be spectroheliograph imaging when those things happened. I already submitted the dopplergram of the filament, but here is a dopplergram of the prominence.
Within a few days, I will post a dopplergram video of 35 scans over 12 minutes. This image is made from a single SHG scan of the h-alpha line and pixel shifted 0.38 Angstroms red and 0.38 Angstroms blue in software.....then combined. It is amazing how much different the prominence looks blueshifted vs. redshifted (blue moving toward us, red moving away).
