@DavidNg Yes it was the brightest pass I've ever seen! So bright that when I first saw it I thought "that can't be it!" and so I was a bit late taking the shot.
@Deeno It was taken on my 5DmkII and 16-35mm f2.8L at 16mm f8 ISO320 15 seconds exposure. Also I've cropped into it a bit and done my usual 16:9 crop (I find it more pleasant as I've got used to it during my years working as an animator).
I've attached the next image in sequence taken straight after the one I posted. It is the full frame except for the 16:9 crop. I wish I'd started the sequence a little earlier to get the full pass over the city but as I said I was still setting up and didn't recognise it at first.
