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

237UAP00086 has too little discriminating evidence for a named identification. It is not treated as evidence of exotic activity; it is classified as insufficient/low-value until better sensor, aircraft, or weather data is available.

1.1 Key Findings

1.2 Bottom Line

INSUFFICIENT / LOW ANOMALY VALUE: The report does not contain enough discriminating evidence for a named identification. It is not treated as evidence of exotic activity; it is a low-value insufficient case unless stronger sensor data appears.

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 matchingAircraft off the OWB228068 at FL370 heading 041 at 504 knots reporting observing 60-80 miles ahead and altitude very high above them several lights doing an orbit. ZME controllers have no radar depicting any activity in the vicinity at any altitude. FDX1 is at FL380 off the OWB333033 SW bound at FL380. ZME will inquire of FDX1 any anomalies in the area to attempt to correlate the sighting. 0809 FDX1 reported no anomalies sighted during their flight in the vicinity described by AMX692. FDX1 was approximately 70 miles W of Louisville, SW bound. ZME will file an MOR for record. AWO notified.

4. Methodology

  1. 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.
  2. External object dataset. The object layer used historical Space-Track/TLE-derived Starlink element rows. The analytic mode for this case is historical Starlink element propagation and same-launch/designator sky grouping.
  3. 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.
  4. 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.
  5. 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.
  6. 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.

Starlink catalog IDs considered2107Historical element rows2107
Above horizon at report minute112At/above 10 deg51
Largest same-sky cluster18

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.

surface visibility ranged 10-10 statute miles; precipitation was reported in at least one observation; low/broken/overcast cloud layers were present in at least one observation. Surface ASOS/METAR observations describe airport-level weather and visibility; they do not by themselves prove conditions at the sighting altitude or line of sight.

5.16 NOAA IGRA Radiosonde Wind Profile

Nearest sounding implies mean 0-12 km wind drift toward 71.9 deg at 25.75 m/s; a passive balloon could drift about 185.4 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.

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 LayerStatusCase-Specific Note
NARA public UAP/FAA reportreviewedSource IDs: 237UAP00086

Space-Track SATCAT metadatascreened30 NORAD IDs checked; 30 matched in local SATCAT subset
Launch-object/SupGP layernot applicablenot a launch-object case
NASA/JPL known small-body layernot selectedCAD/Horizons secondary screen included when this case had NEO-relevant timing/geometry
NASA POWER/Horizons/DONKI contextscreenedHourly weather, sky geometry, and space-weather context where local JSON is present
Aircraft/ADS-B layernot exhaustedADSB.lol historical release pattern is recorded separately; actual aircraft exhaustion requires targeted trace extraction
NOAA GOES imagery layernot exhaustedCloud/lightning imagery layer for the report hour
NOAA GOES ABI/GLM manifestscreenedPublic S3 object listing for the report hour
NOAA/NEXRAD weather radar layernot exhaustedWeather radar only; not ATC/primary radar
NOAA IGRA radiosonde layerscreenedBalloon drift plausibility layer
ASOS/METAR surface weatherscreenedNearest station visibility, cloud, wind, precipitation, and METAR observations
Weather/balloon source planplannedNearest weather-airport, GOES, and radiosonde queries are listed where local plan JSON is present
Final analytic dispositioninsufficient / low anomaly valuePresence-only satellite density is context only; a stronger case-specific fit is required for normal-object disposition
