Celestial & Aerial Signals Program

Night Watch

Pan the real sky, search for a star or constellation, and see where the catalogued detections fall against it. The instrument holds the record and the sky in one view.

Drag to pan · scroll to zoom · click a marker for detail · for the immersive view.

Markers show celestial entries at their recorded positions. Amber markers are events from the published literature; brighter markers are the Laboratories' own entries. Public source records are attached wherever the entry comes from outside the Laboratories. For the complete record, including terrestrial and oceanic detections, see the Persistent Signal Catalog.

Laboratories marker

Gold ring; public FAL coordinate packet.

Literature marker

Amber ring; source-backed published or catalogued position.

Open review halo

Soft halo marks unresolved or under-study entries.

Class III ring

Dashed ring marks retained records with the highest review burden.

Uncertainty ring

Faint dashed ring shows the public coordinate radius when released.

Public horizon

Dashed elevation lines show the public latitude band and 20-degree review mask.

Analyst console

Public dossiers, source matrix, and review queue.

This console is generated from the same public packets as the sky map. It makes the release layer easier to audit: which records have source material, which carry cadence models, which fields are missing, and which sectors of the sky carry the densest public review load.

Public almanac

Derived transit rows for the release packet.

The almanac converts each plotted coordinate packet into a first review window, or a daily peak when no public-latitude window clears the mask. It gives readers a precise way to compare records by altitude, azimuth, cadence phase, and queue pressure without exposing station operations.

Correlation ledger

Pairwise public review, without source claims.

Night Watch now publishes an adjacency ledger for the plotted sky records. The ledger compares public coordinates, reference sectors, cadence fields, and packet completeness so analysts can see why two records should be read together. A high score means review pressure, not shared origin.

Celestial docket

Public sky records with enough position to plot.

The docket below is generated from the same public packet data used by the instrument. The reference sector is a browsing aid computed from constellation centroids, not an official boundary assignment. Transit estimates use the public Calder Ridge latitude band of 41.7 degrees north and signed longitude band-81.2 degrees and do not reveal station geometry.

The public instrument now carries a visible method layer.

Night Watch is meant to be browsed by non-specialists without hiding how the public display is assembled. The interface exposes the same coordinate assumptions, cadence normalization, and ordinary-source checks that govern whether a record can be plotted.

Layer stack
Coordinate packet

Epoch, frame, marker use, public uncertainty radius, and coordinate source are stored per record.

Horizon transform

The map converts R.A./declination into public-latitude altitude and azimuth for any UTC minute.

Cadence model

Published periods are normalized into comparison strips without treating them as live predictions.

Source discipline

Ordinary-source checks and release limits travel with the visible packet instead of living only in prose.

Calculation notes
alt = asin(sin(lat)*sin(dec) + cos(lat)*cos(dec)*cos(HA))

Public altitude and azimuth readout

HA = LST - RA

cycles_per_day = 86400 / period_seconds

What Night Watch is allowed to show

Night Watch is not a live operations screen. It is a public release instrument. A record appears here only when the position, source note, and review language can be shown without overstating what the Laboratories know.

Plot eligibility
Coordinate stability

Public marker requires stable J2000 coordinates or a published coordinate source.

Source provenance

Literature entries retain publisher/source links; FAL entries require a public abstract or finding.

Review state

Class and status are behavior labels, not claims about origin or significance.

Non-sky records

Terrestrial and oceanic entries remain in the catalog rather than being forced onto the sky view.

Report an observation

The Laboratories accept observations from the public. If you have recorded something you cannot explain -- a signal, a sound, a reading that returns -- describe it here. Reports are reviewed by staff. Not every report becomes a catalog entry, but every one is read.

Triage

Staff check for completeness, date, location, instrument context, and ordinary-source notes.

Correlation

Relevant reports may be compared against catalog records, public source material, and instrument schedules.

Follow-up

A staff member may request raw files, calibration notes, or permission to cite the observation.

Catalog review

Only reports with enough evidence and review history are considered for public catalog entry.

Public reports enter a reviewed observation queue. Include enough context for staff to evaluate ordinary explanations before any catalog comparison is attempted. Do not include private third-party recordings unless you have permission to share them.

Optional, if you wish to be contacted.

Use local date if UTC is not known.

Sky reports only.

Sky reports only.

Nearest city, bearing, station, receiver site, or sky direction.

Receiver, camera, audio recorder, telescope, sensor, or unaided observation.

Examples: weather, aircraft, electronics, nearby machinery, known broadcasts, wildlife, neighbors, scheduled work, or calibration activity.

Include duration, recurrence, signal behavior, surrounding conditions, and whether you can provide raw files.
