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
237UAP00628 is assessed as normal-object favored because the available public evidence gives a case-specific ordinary-object candidate: strong ADS-B aircraft candidate N521SY E75L a68e4c at 15.5 km, azimuth 15.0 deg, elevation 36.05 deg, 5.71 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: 2024-05-18T06:50:00+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 N521SY E75L a68e4c at 15.5 km, azimuth 15.0 deg, elevation 36.05 deg, 5.71 min from report.
Non-causal context / rejection screens: very dense orbital-object sky background; context only, not causation.
Remaining hard features: hard maneuver language.
Objects above horizon: 850; at/above 10 deg: 401.
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.

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.

5.9 NASA / NOAA / ADS-B Expansion Layer
This source layer adds free NASA context that was previously missing from most packet cases. It is contextual evidence; it does not replace aircraft, satellite, balloon, or radar causation tests.
Requires targeted extraction from large daily history archives before claiming aircraft exhaustion.
NOAA GOES imagery
not yet exhausted
Needed for cloud/lightning visual context.
NOAA GOES ABI/GLM manifest
screened/present
Public S3 object availability for the report hour.
NOAA NEXRAD weather radar
not yet exhausted
Weather radar only; not ATC radar.
NOAA IGRA radiosonde
screened/present
Needed for balloon drift plausibility.
ASOS/METAR weather observations
screened/present
Nearest station surface observations around report time.
ADSB.lol historical: extract aircraft traces from adsblol/globe_history_2024 for 2024-05-18, then filter +/-60 min and 250 nmi around 30.1963,-98.2401.
NASA POWER/Horizons/DONKI: batch context for 237UAP00628 at 2024-05-18T06:50:00+00:00.
NOAA GOES: pull nearest ABI/GLM products for the UTC hour and render cloud/lightning map.
NOAA NEXRAD: select nearest radar stations and render Level-II/III weather radar sweep around event time.
NOAA IGRA: find nearest radiosonde station launches bracketing the event and model wind drift for balloon-like descriptions.
Space-Track gp_history/decay: fetch exact historical element rows and decay/reentry status for top candidate NORAD IDs.
5.12 Weather, Imagery, and Balloon Query Plan
This plan identifies the concrete free sources needed for the next case-specific weather and balloon checks. These are not treated as completed exclusions until the data are downloaded and plotted.
surface visibility ranged 6-10 statute miles; no precipitation was reported in the retained observations; 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.
Nearest sounding implies mean 0-12 km wind drift toward 38.5 deg at 7.67 m/s; a passive balloon could drift about 55.2 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.

GOES public S3 objects are listed for the report hour where available. This is an availability manifest, not yet a rendered satellite image.
This layer uses the downloaded ADSB.lol daily history archive to test actual aircraft tracks near the report coordinate and minute. It is not treated as a primary-radar substitute; it is a transponder/receiver-derived aircraft screen.

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
237UAP00628 is assessed as normal-object favored because the available public evidence gives a case-specific ordinary-object candidate: strong ADS-B aircraft candidate N521SY E75L a68e4c at 15.5 km, azimuth 15.0 deg, elevation 36.05 deg, 5.71 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.
