Baffling Backslashes

We see below some mysterious orbs I photographed in recent days, all of which have stripes looking like a backslash symbol.

This now makes 19 times that I have photographed mysterious orbs with such a backslash pattern. This is one of 32 repeating patterns of mysterious orbs I have photographed. The visual below shows an example of each of the patterns, and how many times I have photographed each.  Multiple examples of all of these patterns can be seen here.
