A little guidance, a better view

Start with your sky.

Noonfall helps you find a solar eclipse, understand your view, and watch its changing light.

Your first eclipse, in three steps

  1. Choose where you will be

    Use the location button at the top of any page. Search for a city, use your current position, or enter coordinates. You can explore without sharing your location.

  2. Find the eclipse you can see

    My sky finds your next visible eclipse. Eclipses lets you browse upcoming events or choose a year from the archive.

  3. Preview the moment

    Open an event to start at maximum coverage. Drag the timeline, press Play preview, or turn on sound. Choose 600× to watch ten minutes of the event each second.

What you are looking at

Three kinds of eclipse

Total

The Moon completely covers the Sun along a narrow path on Earth.

Annular

The Moon leaves a bright ring of sunlight along the central path.

Partial

The Moon covers part of the Sun. The amount depends on where you are.

What do the times and percentages mean?

Event dates and global maximum times are labelled in UTC. Preview clocks and event contact times use your device’s time zone, shown beside the times. Choosing another city changes the viewing location; it does not change your device’s time zone.

Coverage is the percentage of the Sun’s disc hidden by the Moon at the chosen point. “Maximum” is the greatest coverage during that event. The horizon note tells you if that moment happens below the observer’s horizon.

Is this a live camera or a simulation?

All views are calculated simulations. My sky follows the current time when a local eclipse is near or underway. Event previews and the globe use the time you choose on the timeline. Sound is an artistic interpretation of coverage.

The globe illustrates the shadow’s movement. Its dark patch is not a precise boundary for planning where to see totality.

How is my location used?

Your selected coordinates are saved in this browser and used for calculations on your device. Noonfall only requests your current position when you choose that option. Open the location picker and select Clear location to remove the saved position.

Previously loaded pages and assets may be available offline. New pages or content that has not been cached can still need a connection.

Where do the calculations and imagery come from?

Eclipse positions and timings use Astronomy Engine by Don Cross (MIT licence). The 1900–2100 catalogue is generated from that engine.

City search uses the SimpleMaps World Cities Database (CC BY 4.0). The globe uses NASA Blue Marble imagery. The overview features original Harmonic Waves eclipse artwork.

Noonfall is part of Harmonic Waves.

Before you look up

Protect your eyes.

Ordinary sunglasses are not solar filters. Read the full viewing instructions before watching an eclipse outdoors.
