First time ever capture - thick dark surface blast in calcium light

[Kitsunegari]

First time i have ever seen this recorded in calcium light, and luckily I am the first person to image it!   If you can find it anywhere else, please let me know.

I have monitored solar eruptions for 20 years,  you see this with hydrogen alpha regularly;  and I am very confident when i say that i am the first amateur to ever record this.        

Too bad i was not imaging in high res, this would have been a textbook class capture..

Start(UT)=150059.862

End(UT)=151935.011

What a catch! That would be a "surge", if I'm not mistaken.

Yea i think it is some type of filament surge for sure,   the interesting thing is that it did not appear on SDO; it just looks like two really bright flares;  so this dark eruption is very incredibly rare in calcium light..    

 

I was focused on this massive prominence, so this is what my exposure was set at.

 

 

These dark surges  are very common in H-alpha as seen below;

Nice catch!
