At the link here we have a report of a sighting of an orb with the naked eye:
"In November of 1989, while stationed at Newport Naval Station in Newport, Rhode Island, I encountered an orb that entered the Naval Housing house where my wife, son, and I lived with our dog.
I was temporarily assigned as the Pier Master, with a crew of 4 sailors, responsible for the arrivals and departures of Naval ships and supporting them with pier-side services, including tugboat support and scheduling ships for supply store essentials.
One night at around 3 am, I got up, walked over to the bedroom window, and looked out at the housing area as I occasionally did, as a routine habit. I saw a light shining through the curtain, and as I opened it, there was a ball of light, now known as an orb today, moving back and forth over the houses in the neighborhood. It was looking for something or just observing the different front and back yards and cars in the area. The sudden opening of my curtain, I believed, caught the attention of the Orb.
The Orb suddenly started approaching my way and seemed to increase in speed as it got closer to my window. I was in a two-story housing unit, and the Orb's height soon matched the height of the window. It got closer and hovered through the window into my bedroom. When it entered my room, I stepped back and fell into my bed, and my dog started barking up a storm. A computer on my desk made a loud, metallic 'boing' sound. I looked at my laptop as it made a sound, then at the ball of light. The ball of light was a little larger than a basketball, glowing but not shining as brightly as a flashlight. The outer edges were not defined and looked like a frosted light bulb. You could not see through it, but it was not translucent or opaque. The ball of light hovered at the foot of my bed, nearly up against the wall. It hovered there for less than a minute, enough to take a good look at it.
It suddenly flew out of my bedroom, raced down the hallway, took a 90-degree turn down the stairs across the living room, and, I guess, into the kitchen and out through one of the walls. My dog and I ran after it, followed by my son, who had heard all the commotion, and my wife, who had been in bed.
There was no sign of the light, but my dog was staring at the kitchen door and barking at it continuously until I patted her and calmed her down.
I just sat down at my kitchen table and explained to my wife and son what had just happened. We never talked about it after that night. Not even today. Every time a story or conversation comes up about orbs, my son and I look at each other and nod. A few weeks ago, I finally made a MUFON report and told the MUFON investigator about Orb.
