Thanks for your comment, John. I am fairly sure it was not an F-16 or a drone, considering how far away and high in altitude it was. Much closer to the altitude a satellite might be. Although getting "buzzed" by an F-16 would be kind of cool.

Well, they were thoughts.  I really hope that what you saw was something truly weird, because that would be cool and would expand our understanding. Those things are, obviously, harder to prove.  Still, "weird" does happen.

<p>Sorry, my answer may be a little speculative</p>
<p>I think that the red dot you observed was satellite Cosmos 1959 r, it had the apparent magnitude of 5 (maximum is 6th magnitude in Colorado), it might have appeared bright due to an iridium flare or sattelite flare from the  your parallax (an Iridium flare is a reflection from a bright object, given the albedo is not 0), it may appear as red due to the refraction from dust grains or may be the light source is slightly red shifted. I think that this satellite was the dot, because it was moving very fast, in fact, in only 10 minutes it crossed the horizon and it was moving from north to south too, just as described in the observation</p>
<p>It is unlikely to be a fixed star other wise it would not move, it could be a shooting star/comet too, because though it may seem as not coming in the average speed category of a shooting star, the range stretches from 11 km/h to 70 km/h, so the rate of parallax change or perceptible displacement varies based on their mass, original velocity, etc, with the red appearance due to the refraction spectrum of neighboring dust grains</p>
<p>Hope it solves your observation!</p>

how can it be a comet? Which flares are red?

Thanks, Arjun! I looked up the orbit and it fits the path described. I'm looking to find out where it was exactly on the night of August 3rd. My only concern is the speed at which it moved, and that it was only visible for a very brief second, and across such a short portion of the sky. In videos they move much slower across a wider portion of the sky. This object moved even quicker than time lapse videos of satellites. Every video I can find shows some amount of streaking as they move across the sky, and this object remained a solid red circle with no trail or streaking. Any thoughts?

@Kevin Thanks, I am glad it helped you. I think that the streaks are in the videos, due to the FPS/Frames per second, it is only observed in videos due to the fast speed of the satellite, to the naked eye there are no streaks.

Arjun, yes that could be true. I have one more addition to make, and that is upon looking up the flight path of Cosmos 1959, I noticed that it is moving in the opposite orientation from the object I saw. Cosmos 1959 is moving through the US from south to north, and the object I viewed moved from north to south.

<p>This occurred last night, August 3, 2023 in Boulder, Colorado between 10:00-10:02pm. I was walking my dog and stopped to admire the stars for a minute. I was facing east and saw a red dot move very rapidly from north to south. It came into and out of visibility very quickly, covering a very short span of the sky. It left no trail or wake whatsoever. It was slower than a shooting star, a bit larger too, but much quicker than an airplane.</p>
<p>I am aware the Perseids, Alpha Capricornids, and Delta Aquariids are active right now and mostly visible in my area, but this looked nothing like them in comparison. Would love some further insight into what this object could have been. Thanks!</p>

What kind of red? If like an airplane, then it was an airplane. S it was quicker, it's nothing natural, I assume, maybe a lower-flying plane or drone than a plane at 40000 feet

It was a solid deep red dot, and it did not have any flashing or blinking lights. There was a plane in another portion of the sky and it was quite different and much slower than the object in question. I mean the speed was remarkable, certainly much closer to the speed of a shooting star than any plane or drone I'm aware of.

Meteors run at different speeds. Ball lightening moves slower than a typical meteor.  A plane moving from behind one cloud to another cloud can also explain this.  As far as answering the question, theres not enough info to go on to make a decent answer.

Wow. I just saw the very same thing tonight about 5 min ago! It was a bright red dot. Because it lacked a white light, I knew it was different from a normal plane. Then I noticed it was moving exceptionally faster than a plane. I waited for it to pass the window divider but it didn’t. So, I stood up but it was gone! Never seen anything like it. Strange.

Shaniqua, thanks for sharing! This sounds pretty close to what I saw. It was so fast and was only visible for like one second, I just happened to look up at the right moment. What state did you view this from, and do you recall what direction you were facing?

Hi Kevin, my daughter and I saw something very similar to what you described earlier this week in rural Illinois. Approximately 9-10pm, Sept 12th or 13th. We were facing south. The object was a deep red, did not blink or have any other light. No trail. It moved at the speed of a satellite, by my estimation, at a consistent speed from west to east about 40-50 degrees from the horizon. We saw it for 10-20 seconds and it crossed a large portion of the sky.

Thanks Tom, that does sound very similar to my object. It's really interesting that you were able to view it moving across a large portion of the sky. Mine kind of appeared in the middle of the sky and then disappeared within two seconds max, on a completely clear night! It was about 30-45 degrees from the horizon. I'd like to think they were the same object; have you found any possible leads?

I've seen exactly the same thing but I am in the southern hemisphere in a small town called Somerset East, South Africa, where there is very little light pollution. I've seen this red dot a few times, and it always just vanishes after moving quickly across the sky for a short distance. Last night it moved from south to north. It doesn't look at all like any of the satellites or aircraft I've also observed here. I have no clue what it is but I am guessing it could be a drone, maybe?

That sounds very similar to the object in question. My thoughts on it being a drone are mixed. To me, it appeared to be much higher in the atmosphere than a plane or drone would ever be. It looked much closer to a meteor in size, speed, and distance, but red, and without a streak or trail. Hopefully, this type of object can be captured on video, especially if it occurs frequently around your location in South Africa, because my encounter was very brief (under 2 seconds) and I doubt I'll see it again.
