Introduction


The Total Solar Eclipse of 1997 Mar 09 is visible from the following geographic regions:

  • Partial Eclipse: Asia, Alaska
  • Total Eclipse: Mongolia, China, Siberia

The map to the right depicts the geographic regions of eclipse visibility. Click on the map to enlarge it. For an explanation of the features appearing in the map, see Key to Solar Eclipse Maps.

The instant of greatest eclipse takes place on 1997 Mar 09 at 01:24:51 TD (01:23:48 UT1). This is 0.7 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellation Aquarius. The synodic month in which the eclipse takes place has a Brown Lunation Number of 918.

The eclipse belongs to Saros 120 and is number 60 of 71 eclipses in the series. All eclipses in this series occur at the Moon’s descending node. The Moon moves northward with respect to the node with each succeeding eclipse in the series and gamma increases.

The total solar eclipse of 1997 Mar 09 is followed two weeks later by a partial lunar eclipse on 1997 Mar 24.

These eclipses all take place during a single eclipse season.

The eclipse predictions are given in both Terrestrial Dynamical Time (TD) and Universal Time (UT1). The parameter ΔT is used to convert between these two times (i.e., UT1 = TD - ΔT). ΔT has a value of 62.4 seconds for this eclipse.

The following links provide maps and data for the eclipse.

Eclipse Predictions

Predictions for the Total Solar Eclipse of 1997 Mar 09 were generated using the JPL DE405 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass. The predictions are given in both Terrestrial Dynamical Time (TD) and Universal Time (UT1). The parameter ΔT is used to convert between these two times (i.e., UT1 = TD - ΔT). ΔT has a value of 62.4 seconds for this eclipse.
