On the 5th April 2018, there was a short lived but rather nice odd radius display in Bolton, a town situated in the north west of the United Kingdom. As I was preparing to go to work, I noticed the top of what I initially took to be a 22d halo. However, it rapidly developed and became more complex and very soon an 18d became easily visible to the eye. The display lasted about thirty minutes in total and I was only able to take a few single shots and a couple of stacks before it began to fade and I had to leave. Upon processing the images, 9, 18, 23, 24 and 35d halos with attendant plate arcs were identified as being present.

ReplyDeleteMy best effort to capture the essence of odd radius halos in Berkshire that day. These are stacks of ~200 frames covering ~30 minutes around noon. There were a couple of more UK-based reports of odd radius displays in my social media feed that day.
Nice! So far no odd radius stuff in Ohio USA but am waiting. I still need to get Halo Point
