This is the sixth time I have photographed a mysterious orb with this type of backslash stripe. Conversely, I have 18 times photographed mysterious orbs with a diagonal stripe in the opposite direction (orbs with a stripe that makes a slash rather than a backslash).

The visual below summarizes these patterns and the number of times I have observed them.
