Orange Sky Orbs Typically Act Like Loners

I photograph many orange orbs in the sky, but an orange sky orb will typically appear all by itself, as in the photos below, taken on February 18, 2017, February 11, 2017,  February  3, 2017,  January  15, 2017,  December 29, 2016, December 12, 2016, and  October 25, 2016.

There was no fog, mist, rain or precipitation on these nights.
