I was driving home going south on I-75 in Georgia between Macon and Byron. After coming over slight hill, I noticed a strong golden light hovering over a cloud. Originally, I thought that it might be a beam from the setting sun, but I dismissed that idea, since the light was concentrated in a small area, not stretched across the sky. Then I thought perhaps it was a light reflecting off a plane or something else that usually flies around the area.
The object did not actually move at any point when I was looking at it. Instead, it started pulsing in a way that reminded me of how a flashlight looks when it's going out - it would dim a little, brighten up, dim, brighten and so forth, each time getting smaller until it winked out completely.
Overall, while I was watching it, I didn't feel scared or very special one way or another, as I have while viewing other objects. This one was almost relaxing, and I really was unsure what to make of it.
Some notes on the report:
I am unsure if the object was actually reflecting or making its own light; I am leaning towards making its own light, but I selected both, just in case.
The shape was hard to say - it looked like it had jagged edges, but that could be from casting/reflecting light, so I can't say for certain how it really looked; I checked all that I thought might apply ("flash" is probably the closest option, but it reminded me of a star, too).
The size changed: It started out larger and became smaller, which is why "starlike," "asprin" and "penny" are selected.
The most prominent colour was gold, but "yellow" was the closest listed.
As far as the direction first/last observed, I'm not sure the exact direction, but I was travelling south (it might have been a little west or a little east, but I was definitely going south).
