China Solar Eclipse Path 2009

Eclipse Predictions by Fred Espenak, NASA/GSFC

Observation Site

Our observation site will be located in or near the city of Hangzhou, southwest of Shanghai – the exact location will be confirmed much nearer the day of the eclipse when we can assess the latest weather conditions. Research into weather patterns indicates that this area within the eclipse path has the lowest chance of cloud cover during July 09. Observation sites in the Pacific do not offer improved chances of observing the eclipse and the average 2.5m swell does not make ideal conditions for photography.

Eclipse Coordinates

The eclipse observing site located close to Chang Xing Fan village, has the following coordinates:

• Latitude: 30o 42.2' North
• Longitude: 119o 57.5' East

At this location, mid-eclipse is at 01h 36m 33.3s UT. The width of the shadow is 248.1 kilometres, and the duration of totality is 5m 49s.

From this location at mid-eclipse, the Sun's altitude is 55o, and the azimuth is 98o, i.e. just south of east.

The approximate timings of totality from this location are:

• 2nd contact: 01h 33m 38.6s UT
• mid-eclipse: 01h 36m 33.3s UT
• 3rd contact: 01h 39m 28.0s UT

Note: This is our preferred observation site, but it will be dependent upon weather conditions on the morning of the eclipse and local authorities. Alternative observation sites have been located and details will be provided at the Eclipse briefing.

Qiantang Tidal Bore

Shortly after the eclipse on July 22nd 2009, we will also be able to witness the spectacular tidal bore on the Qiantang River which passes through Hangzhou. This river has the world's largest bore at 9 metres (30ft) high and travelling at 40km per hour, and is one of only four rivers in Asia to have a bore. This event is spectacular and not to be missed – our eclipse observation point will be selected to ensure that we we have time to observe the bore
