Lunar Eclipse Computer: Locations Worldwide

For most U.S. cities and towns, use this alternative form. You can obtain the circumstances of recent and upcoming lunar eclipses for any location, in the U.S. or worldwide, by following these simple steps:

• Select the eclipse from the first pop-up list.
• Specify the location, using latitude and longitude.
• Click the "Get data" button at the end of the form to compute a table of local circumstances.
• Be sure to read Notes on the Data (at the end of the form) for an explanation of the items in the table.

For general information on eclipse circumstances and visibility, see Upcoming Eclipses of the Sun and Moon.

Notes on the Data:

The place name you enter above is merely a title for the table header; you can enter any identifier, or none (avoid using punctuation characters). The data will be calculated for the longitude and latitude you enter above.

The table of local circumstances gives the local time of each eclipse "event" that is visible from the location. The times are the same as those published in The Astronomical Almanac, adjusted to the specified time zone. The altitude and azimuth of the Moon at each of the events is given as well. The azimuth is reckoned eastward from North. The altitude is corrected for refraction assuming standard atmospheric conditions.

The table also gives the time of moonrise immediately preceding, and the time of moonset immediately following, the eclipse. At high latitudes, either or both of these times may be missing from the table. The accuracy of the rise/set times decreases as the latitude approaches +/- 90 degrees. For information on the definitions of terms used, see Rise, Set, and Twilight Definitions.

The times of all events are presented in the standard time of the place requested, using the user-specified zone. Daylight time is not applied.

If you need to check the times of sunrise and sunset around the time of the eclipse, see Complete Sun and Moon Data for One Day.
