Abstract

This case file evaluates a reported UAP sighting against the available orbital-object layer. No compact same-launch group fully identifies the file by itself. The final disposition is assigned under a normal-object favored standard, where ordinary aerospace/orbital explanations are preferred when they reasonably fit the report.

This is a standalone independent analysis prepared from public-source records and public orbital datasets. It is not an official government determination, classification marking, or agency-authored report.

1. Executive Summary

237UAP00320 was screened against historical public LEO catalog objects orbital elements at the extracted time and observer coordinate. The screen did not produce enough mundane evidence to close the case under the normal-object favored standard. Hard features retained for follow-up: radar/primary evidence.

1.1 Key Findings

Source score 50 based on: radar/primary-return language, maneuvering/motion anomaly, UAP/UFO language.
Report time used: 2023-11-22T03:43:00+00:00.
External object layer used: public LEO catalog objects.
Disposition standard: UNRESOLVED requires case-specific causal fit. Satellite density above the horizon is context only and cannot by itself resolve the report.
Case-specific ordinary-object evidence: strong ADS-B aircraft candidate N241WN B737 a235b7 at 15.4 km, azimuth 21.2 deg, elevation 36.05 deg, 3.05 min from report.
Non-causal context / rejection screens: very dense orbital-object sky background; context only, not causation.
Remaining hard features: radar/primary evidence.
Objects above horizon: 1146; at/above 10 deg: 571.
No compact same-launch/designator group survived the report threshold.
No explicit Starlink/balloon wording was found in the source excerpt used for ranking.

1.2 Bottom Line

HIGH-VALUE UNRESOLVED: Hard report features remain after the normal-object screens, such as primary/radar evidence, multiple witnesses, footage references, or motion language that still conflicts with the available object layer.

2. Source Control

The source-control table identifies the public report records reviewed for this case and lists public access links where available. The table is included so this PDF remains interpretable when distributed by itself.

3. Original Report Evidence

Primary excerpt used for matching	Aircraft reported an unidentified aerial phenomenon off the left side while NW bound at FL340, 29NM SE of HCT "on the horizon". The unknown phenomenon was described as 3 white/yellow lights moving up and down vertically, as well as brightening and dimming. ATC facility radar systems showed stationery primary targets in the general vicinity. A person familiar with the area said there is a wind farm in that area.
Report time used	2023-11-22T03:43:00+00:00
Observer coordinate used	40.11170, -100.47743
Observer source basis	aviation_offset:29NM SE of HCT (public text extract 237UAP00320)

4. Methodology

Spacetime extraction. The report time and observer coordinate were extracted from the public text report and normalized to UTC. Aviation fixes/radials were resolved during earlier preprocessing where applicable.
External object dataset. The object layer used historical Space-Track/TLE-derived public LEO catalog objects element rows. The analytic mode for this case is historical public LEO catalog objects element propagation and same-launch/designator sky grouping.
Propagation. Orbital elements were propagated to the report minute and observer location. For launch-object checks, samples around the report minute were retained. For Starlink group checks, objects above the horizon were clustered by sky position and filtered for same-launch groupings.
Comparison. The output was compared against the report's count of lights, direction cue, motion language, altitude/radar language, and whether the file itself already suggested a satellite explanation.
Causation standard. Mere object presence above the horizon is treated as background context only. A normal-object disposition requires a case-specific causal fit, such as a named launch object, a compact same-launch trajectory group, or source language that directly supports that object class.
Disposition assignment. Identified means a specific normal object fits the report spacetime and the hard reported features do not materially conflict. Normal-object favored means a case-specific ordinary aerospace/orbital candidate exists, but it is not a full named identification. Insufficient means the file is too thin to carry high anomaly value. High-value unresolved is used when radar, video, rapid maneuver, or multi-witness features remain after reasonable normal-object checks.

5. External Object Evidence

5.1 Search Volume and Density

This table is a screening layer only. Objects above the horizon show background opportunity; they do not establish causation unless a specific object or compact trajectory group matches the reported behavior.

public LEO catalog objects catalog IDs considered	19898	Historical element rows	19898
Above horizon at report minute	1146	At/above 10 deg	571
Largest same-sky cluster	568

No compact same-launch/designator group survived the report threshold. In this condition, satellite density remains context only and cannot by itself resolve a report with hard features.

5.16 NOAA IGRA Radiosonde Wind Profile

Nearest sounding implies mean 0-12 km wind drift toward 307.4 deg at 12.15 m/s; a passive balloon could drift about 87.5 km in two hours under this crude layer-average model. Radiosonde winds are sparse station soundings; balloon drift remains approximate without launch time, ascent rate, object altitude, and exact line-of-sight bearing.

7. Analytic Comparison

Criterion	Report Evidence	Analytic Treatment
Time constraint	2023-11-22T03:43:00+00:00	Directly used in propagation; this is a hard filter, not descriptive context.

Count / pattern	three-object/light language present	No compact same-launch count match; retained for unresolved report features.
Motion language	moving	Reported motion remains only partly explained; this is a principal reason for high-value unresolved status.
Radar / official check	not specified	Radar or hard maneuvering language is treated as a conflict/collection gap, not hand-waved away.
Analytic disposition	unresolved	237UAP00320 was screened against historical public LEO catalog objects orbital elements at the extracted time and observer coordinate. The screen did not produce enough mundane evidence to close the case under the normal-object favored standard. Hard features retained for follow-up: radar/primary evidence.

8. Caveats, Limitations, and Collection Gaps

No raw cockpit video, ATC replay, radar plot, or witness interview transcript was reviewed unless explicitly stated in the public source text.
Aviation-derived coordinates can represent a nearby fix/radial or report point, not necessarily the actual line-of-sight intercept point.
Starlink visibility depends on illumination, observer altitude, atmospheric conditions, and apparent brightness; this analysis tests geometry, not photometry. No brightness model is used unless explicitly stated elsewhere in the case file.
TLE propagation is appropriate for screening and reconstruction but is not a substitute for authoritative operational ephemerides.
When many satellites are above the horizon, generic presence is weak evidence and is not treated as causation. The report emphasizes named launch-object checks or compact same-launch trajectory groups.
This case is retained as high-value unresolved because the hardest reported behavior is not resolved by the current normal-object layers.

Appendix C. Source Exhaustion Checklist

This checklist records which source layers were actually applied to this individual report. It separates checked evidence from unexhausted collection gaps so the disposition is auditable when the PDF is read alone.

Source Layer	Status	Case-Specific Note
NARA public UAP/FAA report	reviewed	Source IDs: 237UAP00320
Time and observer coordinate	extracted	2023-11-22T03:43:00+00:00 at 40.11170, -100.47743
Orbital object propagation	screened	public LEO catalog objects
Space-Track SATCAT metadata	screened	30 NORAD IDs checked; 30 matched in local SATCAT subset
Launch-object/SupGP layer	not applicable	not a launch-object case
NASA/JPL known small-body layer	not selected	CAD/Horizons secondary screen included when this case had NEO-relevant timing/geometry
NASA POWER/Horizons/DONKI context	not exhausted	Hourly weather, sky geometry, and space-weather context where local JSON is present
Aircraft/ADS-B layer	screened	50769 trace files scanned; 717 tracks retained; aircraft strong candidate present
NOAA GOES imagery layer	not exhausted	Cloud/lightning imagery layer for the report hour
NOAA GOES ABI/GLM manifest	screened	Public S3 object listing for the report hour
NOAA/NEXRAD weather radar layer	not exhausted	Weather radar only; not ATC/primary radar
NOAA IGRA radiosonde layer	screened	Balloon drift plausibility layer
ASOS/METAR surface weather	screened	Nearest station visibility, cloud, wind, precipitation, and METAR observations
Weather/balloon source plan	planned	Nearest weather-airport, GOES, and radiosonde queries are listed where local plan JSON is present
Final analytic disposition	high-value unresolved	Presence-only satellite density is context only; a stronger case-specific fit is required for normal-object disposition
