This page features an interactive Google map  showing the regional visibility of the Annular Solar Eclipse of 2028 Jan 26 . The Google map allows the user to zoom and scroll the map as desired. Clicking the cursor on any location will immediately generate a prediction of the eclipse circumstances from that location. The small global map to the right is for reference and illustrates the overall visibility of the eclipse (for an explanation of this map's features, see Key to Solar Eclipse Maps).
The interactive Google map below uses the Web Mercator projection to display the eclipse track. The large saddle-shapped region is the path of the Moon's penumbral shadow. This is the geographic region from which a partial eclipse can be seen. The northern and/or southern penumbral shadow path limits are plotted as green curves. The magenta loops represent the locus of all locations where the partial eclipse begins or ends at sunrise or sunset. Inside these regions the partial eclipse is in progress at sunrise or sunset. An orange curve also appears inside this region and represents the locus of all locations where the partial eclipse is at its maximum phase at sunrise or sunset. The Key to Google Eclipse Maps illustrates a map with each of these curves. You MUST be somewhere within the region enclosed by these curves in order to see the partial eclipse. Outside this region no eclipse is visible.
The narrow track running through rhe penumbral shadow is the path of the Moon's antumbral shadow. This is the geographic region from which the annular eclipse can be seen. The northern and southern path limits are blue and the central line is red. You MUST be somewhere within the central path (shaded zone framed by the blue lines) to see the annular phase of the eclipse. The eclipse is longest on the central line (red). The yellow lines crossing the path indicate the position of maximum eclipse at 10-minute intervals.
The green marker labeled GE is the point of Greatest Eclipse. The magenta marker labeled GD is the point of Greatest Duration. This is the location where the annular eclipse lasts the longest along the entire path. In this case, the Greatest Duration is 10m30.6s . This prediction does not take into account the mountains and valleys along the edge of the Moon. For the sake of speed and simplicity, the effects of the lunar limb profile are NOT used in the predictions and map presented on this page.
You can be hundreds of miles from the theoretical point of Greatest Duration and still enjoy annularity lasting within a second of the maximum possible (as long as you stay within several miles of the central line). It's much more important to watch the weather forecasts a day or two before the eclipse and choose a location with the best chance of a cloud-free sky during the eclipse. Good weather is the key to successful eclipse viewing - better to see a shorter eclipse from clear sky that a longer eclipse under clouds .
Google Maps uses a close variant of the Mercator projection, and therefore cannot accurately show areas around the poles. As a consequence, eclipse paths at high latitudes will appear highly distorted and may degrade into a series of straight line segments.

The zoom buttons (the 'plus' and 'minus' buttons to the lower right corner of map) are used to change the magnification . The user's cursor can be used for navigating around the map. Just hold the left mouse button down while the cursor is on the map, and drag the map around to reposition it. The two map buttons (top left) let you switch between map view and satellite view.
Click anywhere on the map to add a red marker. A popup window appears above the marker with the calculated eclipse times and duration of annularity for that location (see explanation of Eclipse Circumstances below). The 'x' in the upper right corner of the popup window closes the popup window. Additional markers can be placed anywhere on the map. Move the cursor over a marker to reveal a popup window with the eclipse times for that position. The predictions in the popup window can also be displayed in a new web page via the Eclipse Times Popup button (just below the map and to the right). You can select and copy this infomation to paste into a word processor.
All the markers can be removed by using the Clear Marker button (below the eclipse map). Choose the Large Map check box to produce a bigger map (hint: enlarge the browser window to its maximum size before selecting the Large Map check box). This option is especially useful to users with large monitors.
Below the lower left corner of the map are three readouts. The first gives the geographic coordinates (latitude & longitude) of the map center while the second gives the geographic coordinates of the cursor. The third line gives the distance of the cursor from the last marker. For more information, see Google Eclipse Map Instructions.
When you click on the map a red marker is added and a popup window opens giving the Eclipse Circumstances calculated for that location. The predictions in the popup window can be divided into two sections.
In the top part of the window, the decimal Latitude and Longitude of the marker are given. The Eclipse Type (either total, annular or partial) seen from that position is given. The duration of Totality (or duration of Annularity) lists the length of the total (or annular) phase in minutes and seconds. The Eclipse Magnitude is the fraction of the Sun's diameter eclipsed. The Eclipse Obscuration is the fraction of the Sun's area eclipsed.
The bottom part of the window consists of a table listing the times for important stages of the eclipse. The Event column lists eclipse phase, followed by the date and time (both in Universal Time). Finally, the Altitude and Azimuth of the Sun is given for each event. The altitude is measured from the horizon (0°) to the zenith (90°). The azimuth is measured from due North and rotating eastward (North = 0°, East = 90°, South = 180°, and West = 270°).
Important Note: The eclipse predictions in this interactive map DO NOT include the effects of mountains and valleys along the edge of the Moon. Such corrections for the lunar limb profile may change the contact times and eclipse durations by ~1-3 seconds. The exact location of Greatest Duration may also change by ~10-20 kilometers.

This web page approximates the curved eclipse path by using a series or To maintain the validity of this approximation, the maximum zoom level is limited to ~1 mile/inch (~0.7 kilometers/centimeter). This should prevent over-interpretation of the eclipse path accuracy. You can disable the zoom limit using the link Maximum Zoom to reload the map. ↩

Predictions for the Annular Solar Eclipse of 2028 Jan 26 were generated using the JPL DE406 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass. Although the predictions are first calculated in Terrestrial Dynamical Time (TD), they are then converted to Universal Time (UT1) as presented here. The parameter ΔT is used to convert between the two times (i.e., UT1 = TD - ΔT). For this eclipse ΔT has a value of 73.0 seconds.
The eclipse predictions presented here DO NOT include the effects of mountains and valleys along the edge of the Moon. Such corrections for the lunar limb profile may shift the limits of the eclipse path north or south by ~1-3 kilometers, and change the eclipse duration by ~1-3 seconds.
