The large Prom from this morning.
Lunt 50mm scope & ASI 290MC Camera.
Hope my maths is correct.

Great shot Richard!

In my sketch, I visually estimated ~100000-120000km comparing it's height to the solar radius. I trust your math over my eyeballing so I probably underestimated.

Nice capture Richard - looks like a twister. Cheers John W.

Great capture Richard. We can't believe that prom is still huge and active. Your maths looks pretty correct :)
