Shape: Light
Duration:3 seconds
Two blue lights, one event moving east to west and the other moving north to south.

I was sitting in my backyard at night and saw what I know wasn't an airplane, due to how slow it was moving, I could only see lights. The appearance of the type of light type was that of a filament bulb. They would slowly appear instead of behaving as LED lights do. They would fade, sometimes almost fade away but then slowly brighten up again, going from yellow to more of a red color, no sound. I just assumed it was a weather balloon but I didn't see much information about those having lights on them unless they were in a busy air traffic area.

About 10 minutes after that, moving east to west was what I can only describe as having a lightning bug-like behavior. I'm an amateur entomologist and know they don't fly that high, it was way above the trees (so it appeared to be), I was looking north.

The light lasted about 3 to 5 times longer than the typical length of time a firefly brightens up. It wasn't a comet, much too slow going east to west then rose slightly and wasn't visible anymore. Then it happened again going north to south about 10 minutes later.

The way it behaved, the speed, I just can't describe it. It could have been around 200ft above the ground, small, moving like a fast flying moth. Very similar to what it might look like if somebody put a blue LED light on a drone and flew it over your backyard at night, but completely silent.
