This huge but relatively quiescent prominence actually shows gradual changes.
Here are images of the prominence on the 5th day.

Telescope: AP Starfire EDT 155 mm f/9.  
stopped to 50 mm for disc images, with 4X telecentric lens (f/36) for closeups  
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter  
Camera: Imperx 4M15  
North is up, and east to the left.
