Photo date: February 19, 2017. Photographer: Mark Mahin.
Below is a sky orb orb I photographed on a night with no rain, fog, mist or precipitation.
I have so far taken 14 photos of mysterious orbs that had a diagonal slash that goes from one side of the orb to another, with a resemblance to a slash rather than a backslash. Below are ten of the photos. You can see the original posts in which I published these photos here.
Here are three more photos showing the same pattern:
Below is my updated table listing recurring patterns
in mysterious orbs I have photographed (most of the examples referred to below can be
conveniently seen in this post).
