Light moving west to east.

Solid white light with very slight blue hue, spherical. Light traveled west to east at a steady pace. Speed was faster than an air plane but still easily observable.
Light moved in a fairly direct path, linear, but some slight ups and downs, and gave an impression of floating rather than a planes motion; whisp like.
My first thought was that it could be a drone, but no blinking lights at all, and I had a feeling of excitement, like it was aware of me. (I actually waved) It was pitch dark out last night, and looking at the horizon and tree line today it must have been just above the tree line from my perspective, and must have been rather large or very close.
Closing thoughts; either drone with no blinkers at all, or ET/Spirit. Feeling leans toward non-drone. Also, it was quite stormy around the time of sighting; wind was up, and rain had recently abated.
