Of the photo's I've taken, this is one of my favourites already!
I took it yesterday, between 11am and noon, when my mum and I were out walking my dog, Taela. We had literally an hour of clear-ish sky before the clouds/fog moved back in.
This is certainly not the most distinct sundog I've ever seen, but it's definitely the biggest! And it's the first I've tried taking a photo of!
