# Yellow Sea PR143 Tracking and Surface Controls

## Answer First

PR143 provides a stable raw detection of a dark, approximately oval image feature near the tracking reticle. It is useful as a control against treating every compact sensor silhouette as a resolved vehicle body. The reticle overlays the feature, the background is textured rather than a surveyed fixed landmark, and neither range nor thermometric calibration is supplied here.

## Source Basis

[PR143, Unresolved UAP Report, Yellow Sea, 2023](/?open=Release_6%2FDOD_111985818.mp4) is the Yellow Sea 2023 catalog record. The complete sparse survey is in [C120 - Release 6 Video Corpus Triage](/?open=Release_6%2FAnalysis%2FC120-Release-6-Video-Corpus-Triage.md). This report tests [7.500s](/?open=Release_6%2FDOD_111985818.mp4&t=7.500&preset=raw), [7.750s](/?open=Release_6%2FDOD_111985818.mp4&t=7.750&preset=raw), [8.000s](/?open=Release_6%2FDOD_111985818.mp4&t=8.000&preset=raw), [8.250s](/?open=Release_6%2FDOD_111985818.mp4&t=8.250&preset=raw), [8.500s](/?open=Release_6%2FDOD_111985818.mp4&t=8.500&preset=raw). These are five 0.25-second-spaced samples, not every frame.

**Raw source inspection aid.** Fixed raw ROI x=781, y=450, width=320, height=180 in the 1920×1080 source. The crosshair passes across the dark return.

## Observation

| Test | Result | Interpretation limit |
| --- | --- | --- |
| Raw persistence | Dark return present in all five samples over one second | Detection alone is not anomaly |
| Appearance | Broadly oval/elongated dark footprint with variable edge detail | Sensor response and blur can define the boundary |
| Reticle relation | Return remains close to the tracking marks | Tracking can hold a moving object nearly stationary on screen |
| Overlay interference | Bright crosshair crosses the return, nearby tracking marks add edges | The line is not an opening, appendage or structural seam |
| Registration | Surface texture provides context but no fixed surveyed tie point | No independent velocity or altitude is recovered |

There is no reliable source basis here to call the surrounding brightness a physical field, wake or propulsion envelope. Darkness is a display intensity; without polarity and calibration it is not an absolute temperature measurement.

## Comparison Controls

[PR144, Unresolved UAP Report, Yellow Sea, 2023](/?open=Release_6%2FDOD_111985820.mp4) and [PR152, Unresolved UAP Report, Yellow Sea, 2023](/?open=Release_6%2FDOD_111985835.mp4) contain cloud/sea views with point-like returns and changing tracking context. [PR148, Unresolved UAP Report, East China Sea, 2023](/?open=Release_6%2FDOD_111985821.mp4) includes a recognizable vessel early and a small dark return later. [PR150, Unresolved UAP Report, Yellow Sea, 2023](/?open=Release_6%2FDOD_111985822.mp4) includes substantial display changes. [PR151, Unresolved UAP Report, Yellow Sea, 2023](/?open=Release_6%2FDOD_111985832.mp4) is dominated by texture and the reticle in this survey. These are useful controls for apparent contrast and acquisition, but catalog co-location does not make them synchronized views of PR143.

## Explanation Lanes

**Ordinary:** a conventional object imaged with limited resolution, tracking stabilization and contrast mapping. Birds, balloons and aircraft remain comparison classes, not asserted identifications.

**Disclosure-forward:** a compact vehicle with unusual properties remains possible if later calibrated geometry establishes behavior or structure that defeats those controls. The tested silhouette alone does not distinguish this model.

## Working Assessment

The strongest source-backed result is persistent raw detection, with physical hull and performance interpretation held open. The neutrality gate is satisfied by retaining both lanes and specifying the missing evidence. This is a bounded tracking/appearance study, not a solved identification or full physical-motion promotion.

## Follow-Up

Recover pointing, polarity, gain, focal length and range; inspect native cadence; isolate overlays before any boundary measurements; and establish background registration to a fixed feature. A conventional optical/kinematic match weakens an exotic interpretation. Independent resolved structure or calibrated unusual dynamics would strengthen it.
