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

237UAP00337 is assessed as normal-object favored because the available public evidence gives a case-specific ordinary-object candidate: strong ADS-B aircraft candidate N261WN B737 a284b5 at 17.4 km, azimuth 358.4 deg, elevation 30.26 deg, 1.67 min from report. Dense satellite presence alone is not treated as causation in this packet.

1.1 Key Findings

Source score 54 based on: radar/primary-return language, negative official correlation, UAP/UFO language.
Report time used: 2024-01-13T20:26:00+00:00.
External object layer used: public LEO catalog objects.
Disposition standard: NORMAL-OBJECT 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 N261WN B737 a284b5 at 17.4 km, azimuth 358.4 deg, elevation 30.26 deg, 1.67 min from report.
Non-causal context / rejection screens: very dense orbital-object sky background; context only, not causation.
Objects above horizon: 911; at/above 10 deg: 430.
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

NORMAL-OBJECT FAVORED: A case-specific ordinary-object candidate exists from source language, orbital geometry, launch-object context, or compact trajectory grouping. Dense ordinary sky traffic alone is not treated as causation.

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 right side while E bound at 7,000 feet, 16 NM SE of SAT. The unknown phenomenon was white and blue in color at approximately 7,000 feet. No evasive action. No impact to operation. The UAP was not observed on ATC facility radar system.
Report time used	2024-01-13T20:26:00+00:00
Observer coordinate used	29.45539, -98.24490
Observer source basis	aviation_offset:16 NM SE of SAT (public text extract 237UAP00337)

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	19577	Historical element rows	19577
Above horizon at report minute	911	At/above 10 deg	430
Largest same-sky cluster	430

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 308.0 deg at 10.2 m/s; a passive balloon could drift about 73.4 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.

6. Annotated Evidence Figure

Annotated orbital object figure — Generated figure copied from the local evidence-plot output. It is included as an analytic visualization, not as original sensor imagery.

7. Analytic Comparison

Criterion	Report Evidence	Analytic Treatment
Time constraint	2024-01-13T20:26:00+00:00	Directly used in propagation; this is a hard filter, not descriptive context.
Location constraint	29.45539, -98.24490	Directly used as observer point for azimuth/elevation/range computation.
Count / pattern	not explicit	No compact same-launch count match; retained for unresolved report features.
Motion language	not explicit	Apparent motion labels in the object table provide a plausible but not definitive comparison.
Radar / official check	not observed on ATC radar	No ATC radar return can be consistent with distant orbital objects or visual aircraft-light hypotheses, but it does not prove the match.
Analytic disposition	normal-object	237UAP00337 is assessed as normal-object favored because the available public evidence gives a case-specific ordinary-object candidate: strong ADS-B aircraft candidate N261WN B737 a284b5 at 17.4 km, azimuth 358.4 deg, elevation 30.26 deg, 1.67 min from report. Dense satellite presence alone is not treated as causation in this packet.

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.
Normal-object favored is not the same as a perfect named-object identification; it requires a case-specific ordinary-object candidate stronger than simple object density.

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: 237UAP00337
Time and observer coordinate	extracted	2024-01-13T20:26:00+00:00 at 29.45539, -98.24490
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	screened	Hourly weather, sky geometry, and space-weather context where local JSON is present
Aircraft/ADS-B layer	screened	26399 trace files scanned; 1200 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	normal-object favored	Presence-only satellite density is context only; a stronger case-specific fit is required for normal-object disposition
