I happened to be imaging accidentally the Sun with my Ha-setup on July 31st 2020 at the same time when SpaceWeather wrote about it that "This prominence has just erupted!"
Here's my first image taken at 11:40 AM (UT) with summer time calculated, locally it was mid afternoon at 14:40 ie. 2:40 PM). Please excuse the image file names, I forgot there the summer time in my conversion).
2nd image at 11:41 AM (UT):
3rd image at 11:44 AM (UT):
Question: is this kind of rapid plasma movement normal in such plasma eruptions?
I mean, it seems very much like I have captured plasma movement downwards towards the surface of Sun between my images (=in a couple of minutes time interval only)...
If you look at the plasma blop locations between images #1 and #2 you will get that kind of impression.
Here's an additional image showing all three images in one (for image comparison).
I have saved my original SER files as resized AVI versions here (conversion and resizing done with SER Player):
210 MB (220 868 596 bytes, 800x535 pixels)
817 MB (857 340 284 bytes, 800x535 pixels)
688 MB (721 616 836 bytes, 600x601 pixels)
You can download them and put into AutoStakkert 3 for normal solar Ha-stacking routines, I think. The original SER videos were 2744x1836 pixels and stacked and drizzled 1.5x in AS3 to get these images. The last SER file had 1832x1836 pixels. Those Ha images from my setup can be seen also here: https://spaceweather...pload_id=167078
Also pelase correct me, if there's some systematic error with these Ha images, because I haven't ever seen such fast plasma movement.
Thanks for looking!
