Huge Solar Prominence 10/22/2023 by Greg Cisko, on Flickr
I am not sure scientifically as I never looked it up. But from what I have seen over the years, any prom can be there for some time (like hours) but the shape of it may change within minutes. So that is why a long exposure may not be optimal. Generally if you check see it when you first set up your gear, it will still be there by the time you get your imaging gear all setup.JSBach1801 wrote: ↑Mon Oct 23, 2023 5:43 pm That's awesome. How long does a prominence like that last for?
