Experience the eclipse. Contribute to science.

Use the HALO Eclipse Moments App during the total solar eclipse of 12 August 2026 and help us explore how people collectively experience totality.

Join HALO on 12 August 2026

HALO invites eclipse observers to share a few brief impressions before, during and after totality. By taking part, you help create a collective record of how people experience one of nature’s most extraordinary events.

In return, the app offers practical guidance to help you prepare, look beyond the Sun itself and make the most of this extraordinary moment.
