Moss Vale Weather Station - Solar Eclipses
Moss Vale Weather Station - Solar Eclipses
| Col | Heading | Definition/Description |
|---|---|---|
| 1 | Date | Calendar Date at instant of Maximum Eclipse. Gregorian Calendar is used for dates after 1582 Oct 15. Julian Calendar is used for dates before 1582 Oct 04. |
| 2 | Eclipse Type | Eclipse Type where: P = Partial Eclipse. A = Annular Eclipse. T = Total Eclipse. |
| 3 | Partial Eclipse Begins | Local Time when partial eclipse begins. |
| 4 | Sun Alt | Sun's altitude (in degrees) when partial eclipse begins. |
| 5 | A or T Eclipse Begins | Local Time when annular or total eclipse begins. |
| 6 | Maximum Eclipse | Local Time at maximum eclipse. |
| 7 | Sun Alt | Sun's altitude (in degrees) at maximum eclipse. |
| 8 | Sun Azi | Sun's azimuth (in degrees) at maximum eclipse. |
| 9 | A or T Eclipse Ends | Local Time when annular or total eclipse ends. |
| 10 | Partial Eclipse Ends | Local Time when partial eclipse ends. |
| 11 | Sun Alt | Sun's altitude (in degrees) when partial eclipse ends. |
| 12 | Eclipse Mag. | Eclipse magnitude is the fraction of the Sun's DIAMETER obscured by the Moon. For annular eclipses, it is less than 1.0. For total eclipses, it is greater than or equal to 1.0. |
| 13 | Eclipse Obs. | Eclipse obscuration is the fraction of the Sun's AREA obscured by the Moon. |
| 14 | A or T Eclipse Duration | Duration of total or annular phase of the eclipse (in minutes and seconds). |
The Eclipse Explorer is based on the JavaScript Solar Eclipse Calculator created by Chris O'Byrne and Stephen McCann. The original calculator predicts the local circumstances for any single eclipse over the period 1970 to 2039 for a geographic position supplied by the user.
The Eclipse Explorer presented here features drop-down menus for city coordinates and buttons to select any century from -1499 to 3000 (1500 BCE to 3000 CE). It can be used to explore the frequencey and circumstances of all solar eclipses visible from any location on Earth. The Eclipse Explorer was developed by Chris O'Byrne and Fred Espenak.
The Besselian elements and values of ΔT used in Solar Eclipse Explorer are the same as those used by Five Millennium Canon of Solar Eclipses: -1999 to +3000. For the purposes of calculating eclipse circumstances from a given place, the growing uncertainty in the value of ΔT and the corresponding longitude become unacceptably large outside time period of -1499 to 3000 (1500 BCE to 3000 CE).
