How to Use: Lunar Eclipse Page

The animation at the top indicates what the eclipse looks like on the night side of Earth. The date and time shown in the top-right corner of the animation is Coordinated Universal Time (UTC).

• Click on the play button to start the animation and use the progress bar to fast forward or rewind.
• To show or hide the perimeter of the Earth's shadows, click on the symbol showing two circles on the right of the progress bar.
• To see the animation in full-screen mode, click the rectangle in the bottom-right corner of the animation.
• If a lunar eclipse is in progress while you view the page, LIVE at the bottom of the animation turns red and the animation shows the current stage of the eclipse in real-time.

Follow the link to discover if this eclipse can be seen where you are, an animation showing what the eclipse looks like, if visible, as well as local start and end times, and more.

The interactive Eclipse Map shows the path of the eclipse in great detail. It allows you to select any location to see when the eclipse starts and ends there, and how it looks. Questions about the Eclipse Map?

The 3D Eclipse Globe shows the eclipse path on a globe. Questions about the 3D Eclipse Globe?

The world map below the animation shows where the lunar eclipse is visible. The different shadings indicate various degrees of visibility. For an explanation of the colors, please see the legend below the map.

To see an animated version of the world map, click on Animation above it. Here, the darkest shading indicates night, which is also the area where the eclipse is visible.

The table at the bottom provides global start and end times for the eclipse and its stages. The time is displayed in both Coordinated Universal Time (UTC) and the local time in your home location.

Please note that this table does not take into account if the eclipse is visible in your location.

If you are looking at a penumbral lunar eclipse, please note that these only involve the Earth's penumbra, which is a much lighter shadow than the umbra, so it may be difficult to spot. That's why penumbral lunar eclipses are sometimes difficult to distinguish from a normal Full Moon.

If the eclipse you are witnessing is a total or partial lunar eclipse, note that these kinds of eclipses always begin with a penumbral eclipse, which is hard to spot. Just wait a little longer until the Earth's umbra falls on the Moon. See the Eclipse City Page for your location to find the local time for when that will happen.

If the eclipse you are witnessing is a penumbral lunar eclipse, please note that this type of eclipse only involves the Earth's penumbra, the light outer portion of its shadow. That's why a penumbral lunar eclipse is sometimes difficult to distinguish from a normal Full Moon.

If it's a total or partial lunar eclipse, note that these kinds of eclipses always begin with a penumbral eclipse, which is hard to spot. Just wait a little longer until the Earth's umbra falls on the Moon. See the Eclipse City Page for your location to find out when that will occur.

The Lunar Eclipse Preview lists all lunar eclipses, even the ones not visible from your location. This means that the eclipse, or perhaps only the beginning of the eclipse, may not be visible in your location. To check, please click on Is this eclipse visible in...? at the top of the page. Alternatively, enter any location into the Find Eclipses in Your City field on the right side.

Once a lunar eclipse is underway, the animation switches to a real-time representation of what it looks like on the night side of Earth, assuming the skies are clear. In that case, both LIVE at the bottom of the animation and the dot next to it turn red to indicate real-time mode.

The animation does not show live imagery but tracks the progress of the eclipse in real-time. However, we offer a live stream, including footage, commentary, and background information, for some eclipses in our LIVE Event Center.

We support both 24-hour and 12-hour (am/pm) clock formats. To change the format, please go to My Units and make a selection in the Time Format drop-down.

Please note that, following the internationally accepted convention, UTC times are always displayed using the 24-hour format.

Our database of locations includes thousands of cities worldwide, and we now offer an additional 6 million places via the GeoNames database. If you still don't find your town, please let us know, and we will consider adding it.

Click on Is this eclipse visible in...? at the top of the page. Alternatively, enter any location into the Find Eclipses in Your City field on the right side.

They are 2 of the 3 portions of Earth's shadow. The umbra is the dark central part that is involved in total and partial lunar eclipses. The penumbra is the lighter outer part of the shadow, which creates penumbral lunar eclipses but also falls on the Moon during total or partial lunar eclipses.

The third part of Earth's shadow, its antumbra, is never involved in lunar eclipses.

You will find an explanation of eclipse magnitudes here.

It's the moment when the Moon is closest to the center of the Earth's shadow, and the eclipse reaches its maximum magnitude.
