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

237UAP00367 is assessed as normal-object favored because the available public evidence gives a case-specific ordinary-object candidate: strong ADS-B aircraft candidate EC-NVR A359 347343 at 24.9 km, azimuth 163.9 deg, elevation 25.49 deg, 2.54 min from report. Dense satellite presence alone is not treated as causation in this packet.

1.1 Key Findings

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 matchingAircraft reported an unidentified aerial phenomenon while NE bound at FL260, 10NM N of ORL. The unknown phenomenon was 5 white lights above the aircraft not moving. The UAP was not observed on ATC facility radar system.
Report time used2024-04-08T03:47:00+00:00
Observer coordinate used28.70925, -81.33500
Observer source basisaviation_offset:10NM N of ORL (public text extract 237UAP00367)

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 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.
  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.

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; no precipitation was reported in the retained observations; no low broken/overcast cloud ceiling was evident in the retained station observations. 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 115.4 deg at 16.26 m/s; a passive balloon could drift about 117.1 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: 237UAP00367
Time and observer coordinateextracted2024-04-08T03:47:00+00:00 at 28.70925, -81.33500
Orbital object propagationscreenedpublic LEO catalog objects
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 layerscreened58825 trace files scanned; 650 tracks retained; aircraft strong candidate present
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 dispositionnormal-object favoredPresence-only satellite density is context only; a stronger case-specific fit is required for normal-object disposition
