Heiligenschein is German for “Halo” it is an optical effect that creates a glow of light around the shadow of the viewer's head. It is often known as a hotspot, and is due to the reduction in the proportion of shadows viewed at angles close to the backscatter direction. The characteristics of the surface the shadow falls on can also increase this effect.
So what you are seeing is the drones shadow moving from left to right, the drones shadow is however, to small to see, but obviously not the effect.
See the following image with a larger “drone” shadow.
