Andrea Corsick has some stunning new photos on her Facebook page. In this photo (which requires a Facebook login) she shows an orb with a curved stripe at its bottom. It looks like 10 photos I have taken showing orbs with a curved stripe at the top or bottom, which you can see here. I have a total of more than 70 photos showing mysterious orbs with curved stripes (as you can see here).
