HALO Eclipse Moments
On August 12, 2026, millions of people will witness one of nature's most extraordinary events: a Total Solar Eclipse.
HALO Eclipse Moments helps you prepare, observe and record your personal eclipse experience. Discover what the eclipse will look like from your location, follow every stage of the event, and contribute to a unique international project exploring how people experience totality.
Whether this is your first eclipse or your tenth, HALO helps you make the most of this unforgettable day.
Prepare for Eclipse Day
The weeks before a total solar eclipse are part of the experience.
HALO gradually prepares you for eclipse day with location-based information, practical guidance and interactive moments that help you know what to expect.
Observe the Eclipse
A total solar eclipse is about much more than looking at the Sun.
HALO helps you discover the remarkable changes happening around you—from the changing landscape and sky to unique phenomena such as the Diamond Ring and other moments of totality.
With the Observation Explorer, you'll learn what to look for and when to look for it.
Record Your Experience
Every eclipse is experienced differently.
During and after the eclipse, HALO invites you to record your observations, thoughts and impressions through short surveys and optional audio recordings, creating your own personal eclipse story.
Contribute to Eclipse Research
By participating in HALO, you become part of an international project investigating how people experience total solar eclipses.
Together, participants create a unique collection of observations that will help preserve and better understand this extraordinary natural event.
