The Transit of Venus has been sighted by a New Zealand observer in Tahiti.
The Transit is the passing of Venus across the face of the sun and, depending on the weather, can be visible on Wednesday from New Zealand.
After this time, it will not be seen again until 2117.
Nigel Rankin of New Zealand is in Tahiti in the exact spot where Captain James Cook stood to observe the transit in 1769.
He says the Transit is now in full view, with hundreds of school children and adults from around the world gathering to see the event.
Observers on seven continents, including Antarctica will be able to see parts of the seven hour transit.
However, cloud cover has stopped people in New Zealand seeing the event.
