About Chasing Eclipses

Chasing Eclipses is an independent guide to solar eclipses: when and where they happen, how they work, and the stories of the great eclipses of the past.

A total eclipse is one of the most extraordinary things a person can see, and one of the easiest to miss. The path of totality is narrow, the clock is unforgiving, and a short drive can be the difference between a bright partial eclipse and two minutes of darkness at midday. We built this site to make that difference clear to everyone, not only to astronomers.

What you will find here

• An eclipse calendar to 2045, with a map of every path.
• Detailed guides to the total eclipse of 2 August 2027, with local times, duration and travel advice for each town.
• Explainers on how eclipses work and what you will see, and stories from the history of eclipses.
• A practical eye safety guide based on the advice of scientific and medical bodies.

How we work

Every time, duration and Sun height on the site comes from original calculations, made separately for each town in the guides. Everything else, from travel rules to the records of ancient eclipses, is checked against published reporting and research, with the sources named at the end of each guide. When better information changes a figure, the page is corrected.
