FRB 20200120E

A nearby repeating fast radio burst source localized to a globular cluster in the M81 system. The old stellar environment makes it a high-value comparison record for source-context discipline.

Processing notes

  • VLBI localization review
  • burst arrival-time and fluence comparison
  • host-environment crosswalk
  • nearby-FRB population comparison

Ordinary-source checks

  • globular-cluster association complicates young-magnetar-only explanations
  • public record separates localization from mechanism
  • burst energetics are compared against other repeaters

Release limits

  • public marker follows the published localization
  • no proprietary observing cadence is included
  • environmental interpretation remains under study
