Interactive Eclipse Path
Click anywhere on the path viewer for the local circumstances of the 22 July 2028 total solar eclipse — contact times, duration of totality, obscuration, and the Sun's elevation.
How to use the path viewer
Click or tap any point on the eclipse track to drop a marker and read its local circumstances. On a keyboard, focus the path graphic and press Enter to query the centre of the corridor. The Use my location button reads your device's location (with permission) and plots it on the path. Nothing you enter leaves your browser — the viewer and the calculations are fully self-hosted, with no tile servers, API keys, or tracking.
What the numbers mean
- Magnitude — the fraction of the Sun's diameter covered at maximum. A value of 1.0 or more means the Sun is completely covered: you are in the path of totality.
- Obscuration — the fraction of the Sun's area covered at maximum.
- Sun elevation — how high the Sun sits above the horizon at maximum eclipse. The 2028 event is an early-afternoon, low-winter-Sun eclipse, so a clear view toward the Sun matters.
- Contact times — first contact (partial begins), the totality window (if any), maximum, and last contact (partial ends), in the location's standard time.
Plan the rest of your day
Once you have a location, check its cloud-cover prospects, read the eclipse-glasses safety guide before you go, and browse the detailed city guides. If you experience eye-safety symptoms afterwards, see the eye-safety information.
