Wow indeed! A very unique capture of shadow bands - might well be the first of its kind.
Alex- as Terry pointed out earlier, almost everyone (including myself) who photographed TSE2010 noticed this in their images (since almost everyone had some transparent low cloud of some description). See for example:
Also, while recently in FNQ I was told that someone (can't remember who), upon re-inspecting their photos of TSE20xx (I forget also which eclipse) noticed in retrospect that they indeed captured shadowbands on their images too!
So it turns out 2010 was when this phenomena was first widely observed, but since 2010 it has been discovered on at photographs of at least one previous eclipse.
Thanks very much Geoff, Colin, Mike, Liz, Alex and Geoff! Much appreciated!
It's nice to score another APOD, and that makes it 3 for IceInSpace this week!

It don't think it's just dynamic noise in the image Greg. It only shows up just after C3 and also (weakly) just before C2, but not in any other images. And the banding pattern looks like those that were captured in 2012, especially when viewed at full res. I don't see the same pattern in your image...?

Indeed, thanks for the links. Somehow I missed the 2010 eclipse results and there are some excellent images and videos by you and Joe.
nice collection of pics and congrats on APOD woohooo cheers
Thanks very much Jen!

Thanks very much Rebecca! Try and get to one of these in the future, because these photos don't come close to capturing how beautiful and spectacular it really was visually!
Congratulations Stephen! Just caught up with this thread although I did see your APOD earlier - magnificent!
I caught the 'shadow bands' in 4 consecutive images although nowhere near as clearly as you. Check the second image here: http://www.atoptics.co.uk/fz841.htm
Funnily enough, my sequence of shots through the first Diamond Ring in the 2010 eclipse were almost duplicates of 2012 as the Sun emerged from thin cloud, but there isn't really any sign of similar banding.
The only difference this time was that due to a dreadful clerical error I was shooting at ISO 1600 eek, must have forgotten to wind it back in the heat of the moment! Obviously there are many factors at work - if the bands are projected onto the cloud layer from upper atmosphere effects then ideally the cloud layer should be quite thin and uniform to transmit the bands. Maybe the clouds I imaged through in 2010 were 'fluffier'?? FWIW comparison images are attached.

Congrats again, amazing stuff!
Cheers -
Thanks very much Rob, and well done on capturing the shadow bands as well! Also congrats for the "Optics image of the day"!
It is an interesting difference between 2010 and 2012 - perhaps due to differences in the atmospheric turbulence as well as the cloud thickness? I'm looking forward to the next eclipse to see if they are visible again!
