Another point of view :These orbs are Tig-le
(Cedaredge, CO USA)
Tig-le in the sky on a coudy night.
Tig-les are the energy orbs represented in the Tibetan faith. A concentrated point of awareness pure without form. This Tig-le, visualized as a tiny shimmering ball (when visualized at all), is pure awareness. It is the natural form of our physical awareness. If these are Tig-les then they are beautiful and not harmful in any way.
A similarity in the Hebrew faith is a YOD which could be described as a fiery spark of divine consciousness. I love Tig-les and go out of my way to take photos of them.
HOW TO PHOTOGRAPH A TIG-LE: Choose a dark place outside in the evening. Use a digital camera with the highest pixels possible. If there is a distance so that the flash does not light up anything it is better. Call the Tig-les to come and get in the picture and you will get more. I have even taken them looking straight up at the sky on a cloudy night. After you take the photo zoom in on it and you will see them. Sometimes there are lots of them and sometimes only a few.
