Was looking at starlink and seen more My friends and I stepped outside to smoke a cigarette we were talking about the paranormal and I looked up and noticed starlink going from west to east at least that’s what we assumed the line of moving stars were and it went on for a while I had pointed out Venus or what I thought was Venus and we all saw it the red ball coming from the north side of star link and the bluish one just appeared on the south side of star link to measure in inches looking up at star link the red one was about a foot away from star link and the bluish one was about 5 inches from star link and both balls Ill say danced around each other for a few seconds and the red on zipped away north west and the bluish one zipped west word and they both just went out like turning the bathroom light off and then we noticed starlink fading away like getting dimmer and also the distance between each light or star or whatever if it wasn’t starlink was getting longer and longer till we didn’t see them anymore.

7 orb moving in tandem in day light, initially thought drones but you can see they’re not normal Initially I thought I was looking at a clock of birds, one that moves in concert but then a bird flew in front of them so I pulled out my camera phone to get a better look. But once I started filming I could see they were not birds, no wing flapping and I’m close enough and have filmed at this distance to know I would be able to see those details. I followed them for about a minute but towards the middle you can see they bunch up, then one of the back orbs takes the place of a front then they continue on.
I would guess they were initially heading north, then started to head west/northwest as i could no longer see them as I was filming but once I reviewed it I could see they were barely visible so likely moving away from me. I have seen other unexplained craft but never in daylight, and never like this it truly shook me to see such clear evidence of something of technical superiority that I couldn’t fathom what it was. Also, it became clear after I started filming that my phone was having a hard time focusing on them which has happened in the past when filming other orbs but I have cropped the video to get a closer look, I have taken screen shots, and I can assure you these are not birds and were moving at a good clip I’m facing the USAFA from my place and have seen many planes moving in my life they were moving at least as fast as a Cessna/training plane if not faster.

Spotted a sphere-like metallic object to the northeast while on the walking path. I was walking northeast along the paved path in the Wagon Trails residential community. As I was nearing the junction of Range Ranch Drive I noticed the object, far off in the distance to the northeast.
It seemed very high up. It was sphere-like with pulsating white lights, not blinking lights like a jet aircraft would have. Its altitude seemed to be too high to be a drone.
It was moving slowly making random movements, not in any straight trajectory like a jet aircraft would. It appeared to roll like a ball while it moved slowly and I could see it's pulsating white lights. No smoke emanated from it, nor any noise of any kind that I could hear.
It was definitely not a typical jet aircraft. It seemed to slow down and become almost stationary as it hovered. From the sidewalk on Range Ranch Drive I tried to take a picture with my smartphone, and started writing down notes on my phone about what I was seeing.
After writing my notes for about 30 seconds or so, I looked up to find it had disappeared without a trace. It was nowhere in sight in any direction. It was 12:45pm at this time.
The sky was perfectly clear today, beautiful with no clouds. The picture I took did not pick up the object. Possibly because I couldn't properly focus the camera or because it was too far away for the camera to register it.

I saw 2 objects above and to the left of me and then they simply disappeared I was traveling East on I-76, I saw two objects maybe a few hundred feet above the ground that were white and oval shaped. I thought they were balloons that were maybe 20 ft apart from each other. And then they started to go down and then they just simply disappeared into the air.
I had no way of gauging size or distance.

I saw 2 potential UAP's, 1 that was a morphing blob and 1 White Cigar I was sitting at my local bus stop and looking North. I noticed a light just hovering there. I pulled out my phone to observe closer with the zoom function.
I noticed the light was morphing upon looking through my camera. There is a bit of black coloration the mass and the majority of it was a shiny silver. I did end up capturing a video of it before my bus got there, but I had to cut it short.
At 50 seconds into my video, I saw a white cigar-shaped craft fly closely underneath the mass. Upon further zooming of my video, (not zooming in the camera) I believe the white cigar was spinning. There was absolutely no sound, exhaust, or any fins I could see on the cigar.

A hand above the horizon, streaking from NE to SW an orange, yellow, round light appaered and disappeared. We were standing in the parking, lot greeting friends when the two of us facing south saw the light. Within two seconds the round, orange, yellow lighted appeared and disappeared.
Streaking from NE to SW, it travel about seven fingers at arms length across the sky before disappearing four fingers above the horizon. It was slightly smaller than a pin head if held at arms length. No sound aside from usual city noise.
I saw it, then the person next to me said, "Did you see that?" To which I said, "Yeah, I'm glad you saw that too." There was a large jet at low altitude in the area, but seemed unrelated and was slowly heading due south. We are in our mid twenties and attending graduate school.

Reflective cube seen rotating in the northern sky. I saw what looked like a silver cube rotating in the northern sky. The object never changed it's position despite a breeze from the west.
I think the object was rotating as it would sometimes catch the suns light and reflect it.

Orb with halo moving NE and then S, about 20 angular degrees per minute, in 90 seconds of time, in S metro Denver at dusk My son and I saw the object at approximately 6:45pm Mountain Std Time. Lighting was nautical going into astronomical twilight in an urban playground 5 miles west of downtown Denver. I first noticed the object as a bright light at ~30 degrees from the horizontal, heading northeast (from the southwest).
Its luminosity exceeded that of Venus but was not as bright as the Moon. The relative angular velocity was consistent with it being an airplane, but this assumes it was at the altitude of an airplane. If it was ~5-8 miles in the sky, I estimate it was traveling ~500 mph.
However, if it was higher in the sky, it would need to be traveling faster to achieve the same angular velocity. The light intensity was continuous (not flickering). What caught my attention was the lack of blinking lights indicative of wings or a rudder that an airplane would have.
I also noticed a spherical halo, a kind of dimmer light surrounding the bright central light, about 2-3 times the diameter of the bright light source. Clouds often produce halo effects. Unlike the main light source, the halo fluctuated somewhat with time, as one might might imagine of an object going in and out of clouds.
About 20 seconds into the observation, I asked my son if he saw it. I wanted to ensure it wasn't only my imagination. Indeed, he could see it.
He asked me about the halo. I said maybe because it was traveling through clouds. However, he pointed out that there were no clouds in the vicinity of the object.
In the twilight, looking west, there were visible stratus clouds close to (but not coinciding with) the object's path that were backlit by the setting sun. The object was not among these clouds. There were two airplanes (with fluctuating tail lights) in the approximate "path" of the object, one headed west with a visible vapor trail and another descending in the opposite direction, probably planning to land at Denver airport.
Neither plane intersected the object, but both were close to doing so. Neither plane appeared to change its course either. After the object was ~45 degrees from the horizontal, it began to gradually turn from east to south.
As it changed direction, it emitted something that looked like fireworks--like the halo was shooting off a sphere of light droplets. My son said, "Hey light is shooting out of it!" The halo-clad light continued south for a few more seconds, and then rapidly dimmed to the point of invisibility, ~20 degrees from the horizontal. The whole event lasted about 90 seconds.
Theories that came to mind: Civilian drone: Unlikely given its brightness, the halo and light ejections, and the intuitive sense that the object was much higher in the sky than a drone. Satellite or ISS: Far brighter than either of these, and I understand orbital trajectories to be elliptical (e.g.
, they don't perceptibly change direction) SpacEx rocket: This seems plausible because two rockets launched yesterday. However, Colorado is far from the California and Florida launch sites, and the first passes of these rockets after launch were not over Colorado. Indeed, it would be useful to know the location of these two rockets at ~6:45pm March 4th 2024 MST because such knowledge would allow one to immediately validate or invalidate this theory.
Shooting star/meteor: Very unlikely given the duration of the event. Other, less likely explanations: ??? Any information would be greatly appreciated. Many people would have had the opportunity to see the event witnessed by my son and me given the urban location, though my son and I are the only ones who were at the park at the time.

White orb descended to 1000 AGL, exploded with a white halo, smoke and changed direction. My wife looking out the window noticed the white orb and asked me if airplanes have blinking lights and I said yes, she said you better come look at this. I came to the window and this white orb was coming towards us on a descending path, from about 20k feet and when it got to about 1000' AGL it exploded with a white halo, smoke and changed direction and accelerated 10x the speed it descended with.
The explosion looked like when a aircraft brakes the sound barrier and that white mist cloud develops.

Saw this object moving VERY fast with NO sound whatsoever Object appeared to be spherical or somewhat elongated, with a skirt at the bottom. Sun reflected off surfaces so I surmised it was made up of square panels. We often see jets landing at DIA and this was not one.
It moved ten times faster and by the 4th second winked out completely. There was no contrail nor sound of any kind. Was a blue sky day and very clear.
Direction was e-s-e. I estimated 5000 feet altitude. I have never seen anything like it before.

Looked out window as approaching DIA, looked down and saw a white pill looking thing below us traveling away from us at high speed Observed white pill looking thing underneath plane on approach to denver several 100 feet below flying at high rate of speed the opposite way of the plane landing. To fast to be drone and in comparison there was a car on the road underneath when I saw it had to be a least a half of the car in length. I thought it possibly be snow goose but no way tge speed it was going it could of been.
Ni exhaust trail, no wings, just a blink in the eye white pill looking thing.

Triangle shape made by 3 lights, the center had no lights. Orb spotted at the same time. I look at the constellation Orion every night while walking my dog.
This night I noticed more “stars” to the SE of the constellation near Sirius, I stared long enough to see movement. There was no sound associated with the sighting. I don’t have noise pollution where I live, if there was sound it would’ve been apparent.
There were 3 lights (similar colors to stars) in the shape of a triangle that moved in unison to the SE of Sirius. It was hard to gauge how far away the object was. After the triangle object left my line of sight, an orb appeared near Orion’s Belt.
It seemed to swirl/dance, the color was yellow/orange. It moved around in the same area then disappeared. I see orbs frequently from my yard as I have very little light pollution even though I’m near a large city.
I live at the base of Cheyenne Mtn, I’m very familiar with known military aircraft, how they sound and fly, also familiar with the difference between satellites and Starlink.

Took my dog to the pong for a restroom break, seen 4 red/blue orbs making a diamond shape but spinning clock wise together, slowly. Red blue orbs, diamond shape, spinning clock wise, slowly, hovered for about 30 seconds, then the spinning sped up , and began to move south, spinning increased, for another minute to 1 and one half minute. 0 noise, but my hair stood up like there was static, and then poof they zoomed off, in a blink of an eye.
Also there was total silence. Once they were gone and I began to head home my dog began acting frightened. Once we got home she was fine and as was I.

Noticed moving lights that would move, then stay stationary for long periods and then form linear patterns. Some were flashing Noticed moving lights that would move, then stay stationary for long periods, and then form linear patterns. Some were flashing at times.
At times they were all moving in different directions independently and other times they would form patterns. One pattern was a formation of 3 and another was a line of 4. That would disappear and reappear in different areas.

We saw what looked like dogfighting spacecraft While flying West at about 30,000 ft we started to see stars that appeared to move they weren't satellites because they kept moving back and forth. Sometimes they got brighter than dimmer. I saw them with my binoculars then tried to capture them with my cell phone.
There were two people in the flight deck that saw them. When zoomed in with my cell phone it looked as if it was some kind of high altitude secret aircraft. As if When we saw the engine it was bright light and dim blue when turned away from us.
There were several that seemed to be circling each other. Some other aircraft on the radio reported seeing them too.

Large chevron shaped object almost overhead on 2-4-24 at 7:55pm I took my dog out in my backyard. It was a clear night no clouds and a lot of stars were visible. I looked up gazing and noticed a large chevron shaped object gliding by from south to north.
It was close to being directly overhead that's how I could see the chevron shape. The color was a dim white almost like a cloud in the night sky. It tracked to the north out of site in about 10 seconds, and made no sound.
No pictures were taken, no time to get a camera.
