FRB 20180916B
A localized repeating fast radio burst whose activity is modulated on a roughly 16.35-day cycle. It is retained because predictable active windows, non-detections, and source localization are central to careful public signal review.

Public packet
- 16.35-day activity-window literature note
- host-galaxy localization summary
- burst and non-detection follow-up ledger
- periodicity interpretation caution
Review controls
- Coordinate source
- Host-galaxy coordinate SDSS J015800.28+654253.0, rounded for public display
- Uncertainty
- Localized FRB field; public marker follows host-galaxy coordinate rounding
- Release state
- External literature case retained for comparison
- Marker use
- host-galaxy coordinate for periodic repeater
Processing notes
- active-window phase comparison
- burst-rate and non-detection review
- multi-observatory follow-up cross-reference
- localized host-galaxy coordinate normalization
Ordinary-source checks
- periodicity is treated as an activity-window model
- non-detections remain part of the review record
- host association does not identify an emission mechanism
Release limits
- periodicity is reported as modulation of burst activity, not source mechanism
- public record excludes unreleased observing proposals and raw follow-up schedules
