Looks like black-hot thermal footage. It seems not to move. I'd suspect something natural, like a cloud.
Most of your red arrows point at the now empty reservoir, where due to that and the river's frontier nature no shipping is expected.Example of cargo vessels in the Dnipro river:

I don't know if there are ships that ran aground when the reservoir fell dry.
Please, take the time to read all posts. ~53m is not the altitude above ground, it is in respect to the take off point, which had an unknown elevation. From the posts above, the reservoir has been initially excluded, Kherson is the most likely location, see example of possible geolocation above. There's no artillery brigade in Odessa for obvious reasons. The display is fully explained in the attached manual and summarised in a previous post, thus it was defined as black hot and the hottest temperature registered was -6°C when the object was zoomed in, the coldest is capped to -20°C.Just to point out that if the altitude of the camera is 53 meters above ground, the horizon would be about 40 km away. It doesn't look to me like there is 45 km of dry land in view, so anything beyond it has to be water. But I'm not experienced in this kind of thing, and I don't know what a dried-up reservoir bed would look like. As this is IR, it would presumably depend on temperature, which I would guess is similar to that of surrounding land (cold, at this time of year in Ukraine). Are we sure the footage is Black Hot? Also, the on-screen data seems to suggest the direction of view is to the south-east, and on a map I don't see a suitable area of open water stretching out to the horizon in that direction, unless the drone is actually closer to Odesa, and looking towards the Black Sea.
Article: 'I use this [infrared, heat vision] filter very often,' the unit drone operator said, 'and just got experience so I can differentiate how bright an object should be according to what temperature.'
Based on that experience, Vadym stated that the UFO was 'was very hot. I'm guessing 20 to 30 degrees [Celsius] hotter than other objects.'
Vadym estimated that the roughly 1,300 ft (400 meters) long UFO was also about 328 feet (100 meters) tall.
It caught on the camera of a commercial DJI brand thermal-imaging drone on February 23, 2024.
The possible craft, spotted around 9:02pm local time, appeared to be approximately 37 to 40 miles away from the soldiers, he said, towards Donetsk Oblast, the southeastern Ukrainian province that has been most dominated by Russia's forces.
how long has the resevoir been empty?at the now empty reservoir,
so over in this area?The 406th Artillery Brigade appear to be operating in the southern part of Kherson
Sorry - I made a double error. Your post saidPlease, take the time to read all posts. ~53m is not the altitude above ground, it is in respect to the take off point, which had an unknown elevation.

There's no artillery brigade in Odessa for obvious reasons.

altitude 105.3m in respect to take off point

I entered the 105.3 meters altitude into the calculator

One potential explanation for the UFO was the well-known optical illusion phenomena called 'Fata Morgana,' a mirror-like atmospheric mirage produced by a 'temperature inversion' of hot air in the upper atmosphere.
But Vadym is adamant that what he saw was real.
'It wasn't a mirage,' Vadym told DailyMail.com, 'because in thermal vision you can't see a mirage. You can see it only with your naked eye.'
Article: 5. Discussion and Conclusions
Examination of the refractive index of air in the VIS and IR leads to the conclusion that thermal IR mirages do occur with similar characteristics to VIS mirages, and without any noticeable dispersion effects that would give rise to spectral variation within the MWIR or LWIR bands. A telescopemounted LWIR camera was used together with VIS cameras to record similar mirages of airplanes landing and taking off. All the usual mirage characteristics that are familiar in the VIS spectral range generally appear in the thermal mirages, except the thermal features arise primarily because of temperature differences, and secondarily because of emissivity differences and reflections.
the compass on the display, if we take his word he was looking toward Donetsk means the drone would have to be well north of Kherson, right?

If the gimbal tilt angle is reading a positive value doesn't that mean it has to be pointed above the horizon? Which would seem to rule out that it's looking down at water on the surface. Am I missing something?
Hard to say from the documentation. The variation would suggest that (if accurate) it's drone relative, and the drone is tilting, perhaps to move, or perhaps because of wind. But we can see it's not reliable by itself.Is it relative to the drone or the horizon?
he display in the drone automatically adjusts the highest temperature in the range in accordance with the highest temperature within the scene at that moment. When the object is zoomed in, the display registers -6°C and moments before it reads -7°C.
Example of scale varying (watch the first 8 seconds, the scale in this example is defined as red hot and the maximum temperature varies from 91°F to 102°F for a deer hide that is at 89.

From the information on the display, there was no wind (the historical meteorological data for the past couple of weeks corroborates) although suspiciously zero at the decimal place, and movement was slow towards the forward-left (<1.8m/s, ~64° with the longitudinal axis, i.e. <0.8m/s fwd, <1.6m/s left) and climbing slowly (<0.7m/s), so it's possible the drone tilted slightly forward and aft as the speed varied.The variation would suggest that (if accurate) it's drone relative, and the drone is tilting, perhaps to move, or perhaps because of wind.

The thermal system is capped to -20°C, thus the -30°C in the range is purely for plotting purposes. It is assigned the colour white but nothing in the scene is expected to be coloured white or too close to white due to the cap. With that said, it's possible that light grey areas are colder than -20°C or even -30°C but the sensor cannot register, thus only temperatures between ~-18°C and ~-5.5°C (~-6°C when the ground is in view) are accurate. The system will also add a margin to the maximum temperature detected in the scene for plotting purposes, perhaps 10% or 15% for the black colour, so the object is probably at most -5.5°C plus the error bar for the sensor, and with the assumption it was calibrated properly.The background appears to be mid-gray? That would be around -18c (0F)?
It's interesting that there was no wind, because in the daily mail article the soldier is apparently quoted as saying there were high windsFrom the information on the display, there was no wind (the historical meteorological data for the past couple of weeks corroborates) although suspiciously zero at the decimal place, and movement was slow towards the forward-left (<1.8m/s, ~64° with the longitudinal axis, i.e. <0.8m/s fwd, <1.6m/s left) and climbing slowly (<0.7m/s), so it's possible the drone tilted slightly forward and aft as the speed varied.
'There was a very strong wind,' Vadym said. 'The wind was flowing into the same direction as we were flying basically.'
That's interesting because the drone was not registering any wind, suspiciously not even a decimal place, and the historical meteorological data for the past week shows 0mph to 7.5mph. Even if the wind was blowing in the direction of travel of the drone, the sensors would pick it up.t's interesting that there was no wind, because in the daily mail article the soldier is apparently quoted as saying there were high winds 'There was a very strong wind,' Vadym said.

i think you may be too far left.I put a point in Google earth to try and work out exactly where this was.....
If this thing is in the river, that would make sense in "black=hot" mode, because the water surface would be colder than the land, thus the river would appear nearly white and thus easily mistaken for "sky".The thermal system is capped to -20°C, thus the -30°C in the range is purely for plotting purposes. It is assigned the colour white but nothing in the scene is expected to be coloured white or too close to white due to the cap.

If it were visible light, maybe, but I'd think that greenhouses would look darker in thermal response because glass is not a perfect insulator for the warmer air on the inside. Please correct me if I'm wrong, as I'm not completely sure about that.Could we be seeing a reflection from a glass greenhouse?
....which puts it right in the middle of these greenhouses. Could we be seeing a reflection from a glass greenhouse?
I tried superimposing a frame on Google Earth for the proposed geolocation, it's a good match and it looks like the object is on land. The opposite margin of the Dnipro river is roughly aligned with the perceived horizon.
its also kinda the shape of this hill that lines up with the edge of the field. this works for me if all the flat land areas are covered in thick fog or snow. ??It certainly has the shape of a greenhouse.
There are many ways an apparent horizon (looks like sky meets land) can be different from the actual horizon (edge of the globe). Fog would be one of these ways. Lack of waves on part of the water is another, see https://www.metabunk.org/threads/debunked-hovering-ship-fata-morgana-or-mirage-false-horizon.9112/ .In the video, the highest altitude in respect to mean sea level was 156.2m. However, knowing the distance to the horizon does not exclude the ability to record an object close to the shore, because it's just a matter of vertical field of view, i.e. depending on the optics, it's possible to see the beach and far into the horizon simultaneously. You are also assuming it was not foggy, but based on the historical meteorological data I linked in my first post, it was foggy in the region in the past couple of weeks.
From what I can tell, the refractive index of air for (near) infrared isn't too different from visible light. I would expect a metereological inversion causing a visible mirage to also be causing one in the infrared, though it might be offset a little.But I'm not sure if a mirage like the Fata Morgana would also be possible to appear on thermal imagery.
Since June 2023. See https://www.metabunk.org/threads/the-kakhovka-dam-collapse.12978/ .how long has the reservoir been empty?
So if it is not ship, could it be a blimp?Assuming my geolocation from above is correct, I tried to work out where the UFO would be in google earth. It appears to be too high to be in the Dnipro river....

Your picture shows the LZ 10 "Schwaben", in commercial service from 1911 to 1912.
If the air is cold and the river atmosphere is moist, that happens often. I used to commute to work across a river valley, and it was quite common for there to be dense fog in the valley while it was perfectly clear at a slightly higher elevation.that seems to imply that the far bank of the river is obscured by mist. Is there a reasonable explanation for why that may be the case?
dont use this as fact...i need to move my drone higher to get the landmarks of the field and roads to line up exact..but i got sick of increasing my height so stopped here...if i go higher to get my lines to line up properly it would be even closer. (red dot is pretty close to ufo size). I dont understand what kind of lens they could be using to have their altitude read as 104 meters??, im ignoring all that and just lining up the video.I'm not clear on how the drone operators determined the distance from the drone to the UAP. If it is closer than they think, it is smaller.
