Instructions

To find the local circumstances of an eclipse, first select the eclipse and then enter your location and time zone information in the Geographic Coordinates section. Then click on the "Calculate Eclipse Circumstances and Start Timers" button. The predicted eclipse circumstances with the countdown timers to each contact events will appear in the table below that button. A diagram showing the position of the Sun and Moon at maximum eclipse will be displayed, and updated in realtime while hovering over the various contact events. A live eclipse diagram is displayed when hovering out of one of the contact events. The Sun’s axis is also shown.

To start with other default geographic or eclipse parameters you can append a query string to this web page URL. The parameters can be specified in any order or can be omitted. It should look something like :
?Eclipse='20080801'&Lat=44.0000000&Lng=94.0000000&Alt=545&TZ='+0800'&DST=0 (example)

Eclipse is a text string specifying the eclipse’s date in the following format YYYYMMDD,
Latitude is a number in decimal notation and is positive in the Northern hemisphere,
Lng for Longitude is a number in decimal notation and is positive if East of Greenwich,
Altitude is a number,
Time Zone is a text string in the following format SHHMM,
DST for Daylight Savings Time is a number (0 for Regular Time, else 1).

To simulate a different date and time setting then the one of your computer, you can also append a query string to this web page URL. Again the parameters can be specified in any order or can be omitted. It should look something like :
?ST=1&sYear=2008&sMonth=8&sDay=1&sHour=11&sMinute=0&sSecond=0 (example)

ST must be set to 1 to simulate a date and time (Universal Time), 0 otherwise (defaults to 0),
sYear is the year of the date to simulate,
sMonth is the month of the date to simulate,
sDay is the day of the date to simulate,
sHour is the hour of the time to simulate,
sMinute is the minute of the time to simulate,
sSecond is the second of the time to simulate,
s10th must be set to 1 to display the 10^th of a second, 0 otherwise (defaults to 1).
