Photo date: April 10, 2017. Photographer: Mark Mahin.
The photo below shows a sky orb I photographed with a stripe resembling a backslash. This is the seventh mysterious orb I have photographed with a backslash stripe in its middle (I've also photographed 22 mysterious orbs with slash stripes in the middle).
There was no fog, mist, rain or precipitation on this night.
The visual below summarizes 19 patterns I have observed in mysterious orbs I have photographed. Examples of the patterns can be conveniently seen in this post.
