MUFON has a witness account of an orb — silver, not orange — that seemed to be aware of the witness:

I had a feeling that it was watching me and left because I noticed it. [MUFON ]

The orb in the above sighting was described as a “metal orb.” My orange orb did not appear to be metal — I don’t know what it was, but it was lit up from within. It too seemed aware of our presence; seemed to be waiting for us, in fact, as well as responding to my thoughts.

The comments to the post on the MUFON site are interesting, including one from an Oregon witness. (We do have a lot of UFO sightings here!)  In an earlier comment, the same witness wrote:

You felt like you were being watched because you were. These are what I call I.G.D.s. (Intelligence. Gathering. Devices.) .   .   .    It was probably attracted by the power line. 

It is possible some orbs, as well as other craft, are attracted to power lines. The orb I saw was first seen nearby KVAL television station.
