how fast do the prominence's move in a solar scope can you physically see them loop as if one was looking at a fire or is it more of a day by day movement?
Trevor is right
however, i have noticed that if i am very careful about how i observe the proms they can sometimes creep over the JND and i can detect subtle changes as they occur. Changes about width of a large prom or its height, but it seems to me it's more often that i notice the change when it is looped, such as one was today.
