Saros 17

Panorama of Solar Eclipses of Saros 17

Introduction

A solar eclipse occurs whenever the Moon's shadow passes across Earth's surface. At least two solar eclipses and as many as five occur every year.

The periodicity and recurrence of solar eclipses is governed by the Saros cycle, a period of approximately 6,585.3 days (18 years 11 days 8 hours). When two eclipses are separated by a period of one Saros, they share a very similar geometry. The two eclipses occur at the same node with the Moon at nearly the same distance from Earth and the same time of year due to a harmonic in three cycles of the Moon's orbit. Thus, the Saros is useful for organizing eclipses into families or series. Each series typically lasts 12 to 13 centuries and contains 70 or more eclipses. Every saros series begins with a number of partial eclipses near one of Earth's polar regions. The series will then produce several dozen central eclipses before ending with a group of partial eclipses near the opposite pole. For more information, see Periodicity of Solar Eclipses.

Panorama of Solar Eclipses of Saros 17

A panorama of all solar eclipses belonging to Saros 17 is presented here. Each map depicts the geographic region of visibility for a single eclipse. For central eclipses, the total or annular path is plotted in either blue (total) or red (annular). The date and time is given for the instant of Greatest Eclipse. Every map serves as a hyperlink to the EclipseWise Prime page for that eclipse where a larger map and complete details for the eclipse can be found. Visit the Key to Solar Eclipse Maps for a detailed explanation of these maps. Near the bottom of the page are a series of hyperlinks for more on solar eclipses.

The exeligmos is a period of three Saros cycles and is equal to approximately 54 years 33 days. Because it is nearly an integral number of days in length, two eclipses separated by 1 exeligmos (= 3 Saroses) not only share all the characterists of a Saros, but also take place in approximately the same geographic location.

The Saros panorama below is arranged in horizontal rows of 3 eclipses. So one eclipse to the left or right is a difference of 1 Saros cycle, and one eclipse above or below is a difference of 1 exeligmos. By scanning a column of the table, it reveals how the geographic visibility of eclipses separated by an exeligmos slowly changes.

Calendar

The Gregorian calendar (also called the Western calendar) is internationally the most widely used civil calendar. It is named for Pope Gregory XIII, who introduced it in 1582. On this website, the Gregorian calendar is used for all calendar dates from 1582 Oct 15 onwards. Before that date, the Julian calendar is used. For more information on this topic, see Calendar Dates.

The Julian calendar does not include the year 0. Thus the year 1 BCE is followed by the year 1 CE (See: BCE/CE Dating Conventions). This is awkward for arithmetic calculations. Years in this catalog are numbered astronomically and include the year 0. Historians should note there is a difference of one year between astronomical dates and BCE dates. Thus, the astronomical year 0 corresponds to 1 BCE, and astronomical year -1 corresponds to 2 BCE, etc..

Eclipse Predictions

The eclipse predictions presented here were generated using the JPL DE406 solar and lunar ephemerides. The lunar coordinates have been calculated with respect to the Moon's Center of Mass.

The largest uncertainty in the eclipse predictions is caused by fluctuations in Earth's rotation due primarily to tidal friction of the Moon. The resultant drift in apparent clock time is expressed as ΔT and is determined as follows:

  1. pre-1950's: ΔT calculated from empirical fits to historical records derived by Morrison and Stephenson (2004)
  2. 1955-present: ΔT obtained from published observations
  3. future: ΔT is extrapolated from current values weighted by the long term trend from tidal effects

A series of polynomial expressions have been derived to simplify the evaluation of ΔT for any time from -2999 to +3000. The uncertainty in ΔT over this period can be estimated from scatter in the measurements.
