Antarctic ‘Ring of Fire’ Eclipse Arrives Tuesday With a Narrow Path of Annularity

A 616-kilometer track over Antarctica restricts on-site viewing, leaving populated regions with only partial phases.

Overview

  • According to official schedules, the eclipse runs from 09:56 to 14:27 UT, with annularity from 11:42 to 12:41 UT and maximum near 12:11 UT.
  • The annular phase will last about 2 minutes 20.9 seconds at peak and belongs to Saros cycle 121.
  • Full annularity is confined to remote Antarctic and Southern Ocean areas, while partial views reach southern Patagonia and parts of southern Africa.
  • Expected partial coverage includes roughly 83% on King George Island, about 11% in Cape Town, and around 5% in Punta Arenas, with up to ~40% in some southern zones.
  • NASA and experts stress ISO-certified eye protection for all viewing, and the agency has not confirmed official live transmission plans for this remote event.
