Yet Another Orb With a J-Like Stripe

 Photo date: September 17, 2025. Photographer: Mark Mahin.

We see below a mysterious orb I photographed indoors. 

The similarity between this orb and an orb I photographed five days earlier is striking. The top of each stripe begins at exactly the same point, a little to the right of the top center point in the circle. Both orbs have a J-shaped shadow stripe. Could the J letter be symbolic? A J could stand for a person, or maybe the month of June or January.
