# PR105 East China Sea 2025 Cloud Track and Contrast Morphology

![Eight-frame cloud-boundary review from 120.142 to 128.142 seconds](/media/Release_4/Analysis/images/dod-111830030-124142-long-review-source-frame-contact-sheet.png)

## Source Basis

The source is [Unresolved UAP Report, East China Sea, 2025 (PR105)](/?open=Release_4%2FDOD_111830030.mp4). Six captured leads requested analysis at [16.532s](/?open=Release_4%2FDOD_111830030.mp4&t=16.532), [19.553s](/?open=Release_4%2FDOD_111830030.mp4&t=19.553), [52.910s](/?open=Release_4%2FDOD_111830030.mp4&t=52.910), [71.911s](/?open=Release_4%2FDOD_111830030.mp4&t=71.911), [124.142s](/?open=Release_4%2FDOD_111830030.mp4&t=124.142), and [126.178s](/?open=Release_4%2FDOD_111830030.mp4&t=126.178). A later frame-capture follow-up requested the "two craft entangled" hypothesis at [45.944s](/?open=Release_4%2FDOD_111830030.mp4&t=45.944&preset=normal&zoom=4.393348345260001&panX=-4822.967872181207&panY=-1957.308113472055&contrast=1.15&brightness=1). The requested windows and observation counts were executed without expanding beyond their submitted limits.

## Observation Register

| Request window | Raw result | Promotion decision |
| --- | --- | --- |
| [16.032s](/?open=Release_4%2FDOD_111830030.mp4&t=16.032) to [17.032s](/?open=Release_4%2FDOD_111830030.mp4&t=17.032) - 8 observations | The submitted crop is dominated by blocky black/white reconstruction and a broad light field; no stable bounded "smokey mass" outline survives the second-by-second source context. | Preserve as a processing/sensor-state example; do not promote morphology. |
| [19.553s](/?open=Release_4%2FDOD_111830030.mp4&t=19.553) - current frame | The submitted high-zoom crop is mostly low-contrast field with display symbology at the edge. | No distinct object geometry is available at this crop. |
| [45.944s](/?open=Release_4%2FDOD_111830030.mp4&t=45.944) - current frame with adjacent-frame check | The submitted crop contains two bright lower-right returns that persist at the edge of the crop across [45.911s](/?open=Release_4%2FDOD_111830030.mp4&t=45.911), [45.944s](/?open=Release_4%2FDOD_111830030.mp4&t=45.944), and [45.977s](/?open=Release_4%2FDOD_111830030.mp4&t=45.977), while the full frame keeps them on a cloud-boundary region rather than as centered, independently tracked contacts. | Paired bright returns are source-visible; "two craft entangled" is not established without independent centroids, calibrated motion, or persistence away from edge/crop/sensor controls. |
| [48.910s](/?open=Release_4%2FDOD_111830030.mp4&t=48.910) to [56.910s](/?open=Release_4%2FDOD_111830030.mp4&t=56.910) - 4 observations | A compact bright contact becomes visible late in the interval and is stronger by [56.910s](/?open=Release_4%2FDOD_111830030.mp4&t=56.910). | Contact/reacquisition is supported; "discharge" is not resolved. |
| [67.911s](/?open=Release_4%2FDOD_111830030.mp4&t=67.911) to [75.911s](/?open=Release_4%2FDOD_111830030.mp4&t=75.911) - 4 observations | A compact contact appears by [73.244s](/?open=Release_4%2FDOD_111830030.mp4&t=73.244) and becomes a bright multi-lobed point-spread shape by [75.911s](/?open=Release_4%2FDOD_111830030.mp4&t=75.911). | A contact is supported; two independently tracked objects are not. |
| [120.142s](/?open=Release_4%2FDOD_111830030.mp4&t=120.142) to [128.142s](/?open=Release_4%2FDOD_111830030.mp4&t=128.142) - 8 observations | A vertically stacked bright contrast contact persists near the reticle, then becomes partially obscured as the bright cloud boundary occupies the same region. | Persistent contact plus cloud-boundary interaction is supported. |
| [126.178s](/?open=Release_4%2FDOD_111830030.mp4&t=126.178) - 1-second retest within the long window | The contact is still visible against/within the bright cloud boundary and then loses separability. | Atmospheric obscuration is supported; "transmedium" is not the correct evidentiary label for air-to-cloud entry. |

## Raw Frame Panels

Full-frame boards: [16-second window](/media/Release_4/Analysis/images/dod-111830030-16532-short-review-source-frame-contact-sheet.png), [single-frame window](/media/Release_4/Analysis/images/dod-111830030-19553-frame-review-source-frame-contact-sheet.png), [45.944-second frame retest](/media/Release_4/Analysis/images/dod-111830030-45944-frame-review-source-frame-contact-sheet.png), [52-second window](/media/Release_4/Analysis/images/dod-111830030-52910-long-review-source-frame-contact-sheet.png), [71-second window](/media/Release_4/Analysis/images/dod-111830030-71911-long-review-source-frame-contact-sheet.png), and [124-second window](/media/Release_4/Analysis/images/dod-111830030-124142-long-review-source-frame-contact-sheet.png). The [submitted crop geometry board](/media/Release_4/Analysis/images/dod-111830030-19553-frame-review-geometry-review.png) for [19.553s](/?open=Release_4%2FDOD_111830030.mp4&t=19.553) is retained as a negative/insufficient-detail control; the [crop retest board](/media/Release_4/Analysis/images/dod-111830030-45944-frame-review-geometry-review.png) for [45.944s](/?open=Release_4%2FDOD_111830030.mp4&t=45.944) preserves the paired bright returns without upgrading them to two craft.

The late interval is the strongest of the submitted leads. The stacked bright morphology persists over adjacent frames, but its lobes are not resolved as separate bodies. As cloud brightness rises behind/around the contact, the same small contrast source becomes harder to segment. That is a real source-state transition, but it does not establish a change of physical medium.

## Native Fiji/ImageJ Clarification

The requested enhancement passes used the fixed `smokey-ir` recipe at three adjacent times per target and one target-time sensitivity variant. Public panels are labeled enhanced inspection aids. Private/local provenance retains the source time, crop, recipe, runtime, and integrity metadata.

| Target | Raw comparison | Fixed-recipe result | Sensitivity result |
| --- | --- | --- | --- |
| [16.532s](/?open=Release_4%2FDOD_111830030.mp4&t=16.532) | [Raw](/media/Release_4/Analysis/images/pr105-16532-raw-source-frame.png) | [Enhanced aid](/media/Release_4/Analysis/images/pr105-16532-smokey-ir-enhanced-inspection-aid.png) retains the broad light field and block boundaries. | [Sensitivity aid](/media/Release_4/Analysis/images/pr105-16532-smokey-ir-sensitivity-enhanced-inspection-aid.png) is materially unchanged; no new bounded object appears. |
| [52.910s](/?open=Release_4%2FDOD_111830030.mp4&t=52.910) | [Raw](/media/Release_4/Analysis/images/pr105-52910-raw-source-frame.png) | [Enhanced aid](/media/Release_4/Analysis/images/pr105-52910-smokey-ir-enhanced-inspection-aid.png) clarifies the local brightness field but not a discharge structure. | [Sensitivity aid](/media/Release_4/Analysis/images/pr105-52910-smokey-ir-sensitivity-enhanced-inspection-aid.png) does not create a stable new feature. |
| [71.911s](/?open=Release_4%2FDOD_111830030.mp4&t=71.911) | [Raw](/media/Release_4/Analysis/images/pr105-71911-raw-source-frame.png) | [Enhanced aid](/media/Release_4/Analysis/images/pr105-71911-smokey-ir-enhanced-inspection-aid.png) remains a low-detail gradient at the exact target. | [Sensitivity aid](/media/Release_4/Analysis/images/pr105-71911-smokey-ir-sensitivity-enhanced-inspection-aid.png) does not resolve two independent bodies. |
| [124.142s](/?open=Release_4%2FDOD_111830030.mp4&t=124.142) | [Raw](/media/Release_4/Analysis/images/pr105-124142-raw-source-frame.png) | [Enhanced aid](/media/Release_4/Analysis/images/pr105-124142-smokey-ir-enhanced-inspection-aid.png) retains the stacked bright contrast contact in all three adjacent frames. | [Sensitivity aid](/media/Release_4/Analysis/images/pr105-124142-smokey-ir-sensitivity-enhanced-inspection-aid.png) preserves the coarse stack while fine edges remain non-diagnostic. |
| [126.178s](/?open=Release_4%2FDOD_111830030.mp4&t=126.178) | [Raw](/media/Release_4/Analysis/images/pr105-126178-raw-source-frame.png) | [Enhanced aid](/media/Release_4/Analysis/images/pr105-126178-smokey-ir-enhanced-inspection-aid.png) retains small bright lobes against the cloud boundary in the adjacent pass. | [Sensitivity aid](/media/Release_4/Analysis/images/pr105-126178-smokey-ir-sensitivity-enhanced-inspection-aid.png) is materially stable; the cloud/object boundary remains unresolved. |

Fiji confirms coarse contrast features that already exist in Raw. It does not recover a hull, exhaust plume, release event, independently moving pair, or separately trackable formation. Enhancement therefore clarifies the visibility limit rather than promoting the stronger labels.

## Hypothesis Tests

| Submitted idea | Source-backed result | Status |
| --- | --- | --- |
| White smokey mass | A broad light field and severe block structure are visible near 16.5s. | Processing/contrast phenomenon remains the strongest description. |
| Two craft entangled | Two bright returns are visible at the lower-right edge of the [45.944s](/?open=Release_4%2FDOD_111830030.mp4&t=45.944) crop and persist across immediate neighbors. | Paired image-plane returns are supported; entanglement or two independent craft are not established. |
| Discharge | Bright compact contact becomes visible late between [48.910s](/?open=Release_4%2FDOD_111830030.mp4&t=48.910) and [56.910s](/?open=Release_4%2FDOD_111830030.mp4&t=56.910). | No separable emitted material or expanding plume is resolved. |
| Two rubber duckies | A multi-lobed point-spread shape appears late between [67.911s](/?open=Release_4%2FDOD_111830030.mp4&t=67.911) and [75.911s](/?open=Release_4%2FDOD_111830030.mp4&t=75.911). | Two physical objects are not independently tracked. |
| Cluster/unit/formation | Three vertically stacked bright lobes persist around [124.142s](/?open=Release_4%2FDOD_111830030.mp4&t=124.142). | Formation is a live image-plane hypothesis, not a confirmed multi-object track. |
| Transmedium into cloud | Contact loses separability at a cloud boundary around [126.178s](/?open=Release_4%2FDOD_111830030.mp4&t=126.178). | Cloud penetration/obscuration is supported; transmedium behavior is not established. |

## Theoretical Scene Panels

| Panel | Interpretive read | Boundary |
| --- | --- | --- |
| A - Persistent contact | A compact source persists near the reticle before the cloud boundary. | Source observation. |
| B - Stacked-lobe geometry | The contact resolves into a vertical stack of bright lobes. | Low-level image morphology; not body count. |
| C - Cloud-boundary transition | The cloud field grows into the contact region and segmentation collapses. | Atmospheric obscuration; not evidence of phase change or medium transition. |
| D - Disclosure-forward field model | A field-coupled craft or coordinated micro-formation could present as multiple thermal/contrast lobes and enter cloud without conventional plume signatures. | Speculative; requires independent tracks, calibrated motion, and persistence through obscuration. |

## Explanation Lanes

| Lane | Fit | Upgrade or falsification test |
| --- | --- | --- |
| Cloud contrast / obscuration | The background structure and contact separability change together. | Stabilize the frame and model cloud-edge motion independently of the contact. |
| Sensor point-spread / compression | Multi-lobed and blocky shapes vary with gain, contrast, and source reconstruction. | Obtain native sensor data before transcoding and compare another sensor. |
| One compact physical target | A persistent contact is visible in multiple windows. | Recover range, track file, angular coordinates, and target classification. |
| Multiple-object formation | Stacked lobes can be pictured as a compact vertical group. | Demonstrate independently persistent centroids and separations across native frames. |
| Field-mediated or unusual craft | Persistent contrast with no resolved conventional silhouette leaves an unusual lane open. | Show calibrated motion or morphology that survives cloud, sensor, and processing controls. |

## Case-Specific Tie-In

This report promotes the PR105 queue in [C82 - Release 4 DVIDS Sensor Media Triage](/?open=Release_4%2FAnalysis%2FC82-Release-4-DVIDS-Sensor-Media-Triage.md) and updates the earlier [C86 - Release 4 Cross-Release Hull and Control Matrix](/?open=Release_4%2FAnalysis%2FC86-Release-4-Cross-Release-Hull-and-Control-Matrix.md) finding at 75.045 seconds. It should be compared with [C08 - Formation Cloud and Atmospheric Interaction](/?open=Release_2%2FAnalysis%2FC08-Formation-Cloud-and-Atmospheric-Interaction.md), while keeping cloud interaction distinct from transmedium claims.

## Working Assessment

PR105 contains a persistent compact contrast contact and a useful cloud-boundary sequence. The strongest claim is not “transmedium,” “discharge,” or “two craft.” It is: **a compact multi-lobed contrast contact persists near the reticle and becomes progressively harder to separate as the cloud boundary occupies the same image region**.

The Disclosure-Forward Neutrality Gate passes. Ordinary sensor/cloud explanations remain active, and formation or field-mediated models remain testable. The unusual lane upgrades only if native frames preserve multiple independent centroids or calibrated motion through the cloud boundary after sensor and platform correction.

## Follow-Up

- Recover the native PR105 sensor export and track data from [120.142s](/?open=Release_4%2FDOD_111830030.mp4&t=120.142) through [128.142s](/?open=Release_4%2FDOD_111830030.mp4&t=128.142).
- Stabilize cloud texture and reticle motion separately, then measure contact centroid and separability.
- Use “cloud penetration” or “cloud-boundary obscuration” unless evidence shows a transition between physically distinct media.
