Photo date: May 26, 2017. Photographer: Mark Mahin.
The top photo below shows a mysterious orb I photographed indoors. Note the strange belt-like feature, which looks almost identical to the stripe in the orb shown in the lower photo (one I took on March 23, 2017, as posted here). This is the 15th time I have photographed a belt-like stripe in a mysterious orb. See here for the other 14 examples.
