Introduction

This interactive Google map[1] shows the path of the Annular Solar Eclipse of 2028 Jan 26. The northern and southern path limits are blue and the central line is red. YouMUST be somewhere within the central path (between the blue lines) to see the annularphase of the eclipse. The eclipse is longest on the central line (red). The yellow lines crossing the path indicate the time and position of maximum eclipse at 10-minute intervals.

The green marker labeledGE is the point ofGreatest Eclipse. The magenta marker labeledGD is the point ofGreatest Duration. This is the location where the annulareclipse lasts the longest along the entire path. In this case, theGreatest 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 thelunar limb profile areNOT used in the predictions and map presented on this page.

You can be hundreds of miles from the theoretical point ofGreatest Duration and still enjoy annularitylasting within a fraction of 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 .

User Directions

The zoom bar (left edge of map) is used to change the magnification[3]. The four-way toggle arrows (upper left corner) are for navigating around the map. You can also move the map center around to reposition it by holding down the left mouse button and dragging.The two map buttons (top right) let you switch betweenmap view andsatellite 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 annularityfor that location (see explanation ofEclipse 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 theEclipse Times Popup button (bottom right). You can select and copy this infomation to paste into a word processor.

All the markers can be removed by using theClear Marker button (below the map). Choose theLarge Map check box to produce a bigger map (hint: enlarge the browser window to its maximum size before selecting theLarge 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 position. The third line gives the distance of the cursor from the last marker. For more information, seeGoogle Eclipse Map Instructions.

Eclipse Circumstances

When you click on the map a red marker is added and a popup window opens giving theEclipse Circumstances calculated for that location. The predictions in the popup window can be divided into two sections.

In the top section, the decimalLatitude andLongitude of the marker are given. TheEclipse Type (eithertotal,annular orpartial) seen from that position is given. TheDuration ofTotality (orDuration ofAnnularity) lists the length of the total (or annular) phase in minutes and seconds. TheEclipse Magnitude is the fraction of the Sun'sdiameter eclipsed. TheEclipse Obscuration is the fraction of the Sun'sarea eclipsed.

The bottom section consists of a table listing the times for important stages of the eclipse. TheEvent column lists eclipse phase, followed by the date and time (both inUniversal Time). Finally, theAltitude andAzimuth 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 mapDO NOT include the effects of mountains and valleys along the edge of the Moon. Such corrections for thelunar limb profile may change the contact times and eclipse durations by ~1-3 seconds. The exact location ofGreatest 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 linkMaximum Zoom to reload the map.↩

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 2028 Jan 26were generated using theVSOP87/ELP2000-85solar and lunar ephemerides and a value of ΔT = 71.9 seconds.

The eclipse predictions presented hereDO NOT include the effects of mountains and valleys along the edge of the Moon. Such corrections for thelunar 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. More detailed predictions including the effects of thelunar limb profile are normally posted 12-18 months before each eclipse,
