Weird Rainbow In Adelaide, Australia November 7, 2017 4 by Mary Maxwell This was in Adelaide around 8.50pm on November 5, 2017. He reports that soon after it there was helicopter activity. Here is Mark’s report: “I was at a mate’s house in Adelaide. The skies are sprayed every day in SA, so in most afternoons/evenings the complete horizon is covered by a misty spray which grows into white fluffy cloud coverage. “Last night a rainbow appeared in the sky as seen on this video, I ran for my camera. It lasted for about 10 minutes and then, as if a light switch was turned off, it disappeared. A couple of minutes before the rainbow disappeared we saw two large white aircraft in the sky.
