That particular AR has moved on!
Every hour, every day is different! That's what makes solar observing so interesting... not like taking the 100th image of M42....
Each prom has it's own character some are very wispy and faint, others show tremendous movement and throw off large lumps of matter as they grow and fade.
There have been some very spectacular animations made using 200 frame AVI's exposed every minute or so... these can easily show the variations in structure, and a prom imaged in the morning may look nothing like the same one imaged later in the day. Magic!!
The surface granulation bubbles and boils; I've just been reading that the average life of a "grain" is about 3 minutes and it's only when they get caught up in a magnetic field that they can clump and show more and more detail; just wait until we have some sunspots to "pull them together"...
A 40mm PST ( or the small Lunt's) will show tremendous amount of surface detail and when combined with a webcam will give very satisfying images.....
I'm a convert to the "bright side"
