Reported morphology
Sphere / orb
Spherical objects and unresolved lights whose apparent boundary is circular.

Overview
‘Orb’ can describe a structured sphere, a distant point source or a luminous image without reliable range. Reports in this category therefore do not necessarily describe the same phenomenon.
Observation and identification
Distance, focus, atmospheric scattering and sensor bloom can turn an unresolved light into an apparently bounded sphere. Structure should be claimed only when the observation or recording resolves it.
The earliest wording, sketches and recordings carry greater evidential weight than later labels or illustrations.
Notable cases
The reported form is material to these cases; the links do not imply a common object or cause.
Comparison cases
These cases bear on perception, geometry or sensor interpretation but are not classified as examples of this form.
Public record
These pages document the institutional and historical record associated with the reports.
Key witnesses
Each dossier separates direct observation from later recollection and interpretation.
Evidence assessment
The present internal record establishes sphere language in specific testimony, most directly at Voronezh, but does not establish a coherent sphere phenomenon. Luminous comparison cases should remain separate unless their records resolve a bounded three-dimensional form.
Source library
Sources are grouped by evidential role. A tier records provenance and directness; it does not determine whether a reported interpretation is correct.
Tier 2 Official and institutional records
- Project Twinkle final report and correspondence — The file documents an instrumented investigation of reported green fireballs and shows the difficulty of deriving structure from luminous observations.
- CIA scientific panel: evidence presented — Contemporary material considered by the Robertson Panel, relevant to the historical treatment of unresolved luminous reports.
Tier 4 Claim history and secondary accounts
- Edward J. Ruppelt: Project Twinkle account — Ruppelt’s account provides institutional context for Project Twinkle and should be read alongside the surviving official file.
