Monster Prominence 26th July

I had read on facebook on saturday afternoon there was a large prominence that was lifting off the sun, but when the clouds finally did clear I thought I had missed it, but cranking up the exposure and gain on the DMK31 and I was surprised at the extent of this cloud of plasma.  At the scale I am imaging at I am working to 1010.3km per pixel, and at 623 pixels long, roughly, that puts the prominence at an estimated 625,000km in length, or if you prefer imperial 390,000 miles, which is nearly twice the distance from the Earth to Moon.
