Introduction

The Solar Eclipse Circumstances Calculator computes the eclipse circumstances for all major cities in a geographic region for the Total Solar Eclipse of 2017 Aug 21 .

Simply follow these instructions:

• Section 1 - Select a Output Time (either Local Standard Time, Daylight Saving Time, or Universal Time (UT1)).
• Section 2 - Select Geographic Region coordinates.
• Section 3 - A table will be generated giving the eclipse circumstances for all cities in the selected geogrphic region.

The generated eclipse circumstances table lists important information about the eclipse for each city:

• The type of eclipse seen from each city (P=Partial, A=Annular, T=Total)
• The times when the partial eclipse begins and ends.
• The times when the total (or annular) eclipse begins and ends.
• The time of maximum eclipse.
• The altitude on the Sun above the horizon (degrees) at each of these times.
• The Eclipse Magnitude at maximum eclipse.
• The Eclipse Obscuration at maximum eclipse.
• The Eclipse Duration of either the total or annular phase (if any).

Note than country names for cities appear as the ISO 3-Letter Country Code Abbreviations (Wikipedia).
