Odd radius display of 7th June 2017 in Pskov Oblast

Each frame covers ten minutes
The first halo, that was recorded by my camera that day, was a lonely unusual ring. This halo had radius about 18 degrees (1), and it was extremely diffuse and weak. It appeared when quite dense and nondescript high clouds crossed the sun. Just after this mysterious halo, a 22 halo appeared accomponied by a few odd radius halos, such as an upper 23 plate arc, 9, 20, 24 and 35 degrees halos.
