GLEAM-X J162759.5-523504.3
A low-frequency radio transient recovered from Murchison Widefield Array survey data. It emitted bright, highly polarized pulses on an unusually long cadence during a limited active interval, then did not persist at the same detectable level.

Public packet
- 18.18-minute cadence source note
- active-interval and non-detection summary
- polarization and low-frequency behavior abstract
- long-period transient comparison file
Review controls
- Coordinate source
- Source designation and public J2000 coordinate rounded from GLEAM-X record
- Uncertainty
- Localized radio transient field; marker follows the published source designation
- Release state
- External literature case retained for comparison
- Marker use
- localized low-frequency radio transient
Processing notes
- low-frequency transient imaging review
- period search against survey cadence
- polarization behavior comparison
- archival non-detection cross-check
Ordinary-source checks
- ordinary pulsar period range comparison
- known variable-source and imaging-artifact checks
- public record avoids assigning a progenitor
Release limits
- included as a long-period transient comparison record
- public marker is a source position, not a mechanism claim
- follow-up non-detections remain part of the packet
