the big prominence and eruptive emission within...(june 23rd)

[ChrisHalpha2017]

hello,

Here in Paris this morning there was a small clearing of the sky that allowed me to see this

There was a Doppler shift at the base that annouced an eruption ; it was pretty small and faint but still I could see it in emission in front of the big prominence.

Can you see that too when you use an H alpha filter (as i dont have one) ?

Very informative images Chris with your explanation.
Thanks for sharing.

I looked at the GOES Flux graph and it does not show an eruption at the time marked on your image but it might have been a fairly bright surge prom that you captured.

can a surge be that big and go that high ?
