Sounds like the CARE experiment.

One thing does come to mind as an explanation. By your description, you may have seen an aircraft flying directly toward you with its landing lights on. The "halo" could have been caused by a light fog or thin cloud. As the plane turned, the light would begin to move and dim until it was no longer visible (as it was no longer pointed in your direction). But, not having seen it, I can't really tell you what you saw.
BTW, Venus is visible in the early morning. Jupiter is the one that's shining at night.
