Photo date: June 15, 2020. Photographer: Mark Mahin.
I took the photos below while photographing only ordinary drops of pure, clean water falling in front of a black featureless background. On this day one of several dramatic patterns I got was one that looked like the orb notches that appeared the previous day (June 14), except that this day's notches were even deeper. The orb notches appeared in almost all of 2000+ consecutive photos, with a total of more than 5000 such orb notches appearing, always on the bottom right of an orb. Below are some examples.
