Hello Ann,

This is an amazing image. Is it right that it shows the same event as the image on the gallery by Chip Stone? Gallery

Yes I think we see a supralateral arc here (among many others). On the gallery it is classified as a 46 degrees halo. Always difficult to distinguish, but a rule of thumb is that the supralateral arc must touch the CZA, while the 46 degrees halo is a bit below. That’s why I think it is supralateral arc.
