Right Place at The Right Time

The picture below may not look like much (see cloud formation in SE QLD), but at ground level and at just the right place it created a perfectly formed jet stream cloud, covering just under half of the sky from visible horizon to horizon. The video I took doesn't do it much justice to what it looked like in real life (view it in full screen if you can), and I apologize for its length as I was already running late for work.
Its not every day you see this, So I thought would share it with ATS!
