The Vela Incident (1979)

posted Monday, 22 September 2014

A double flash characteristic of a nuclear explosion was recorded by the US Department of Defense Vela 6911 satellite in the South Indian Ocean on this day in 1979. No government has officially taken credit for the event, but it is generally thought to have been a joint Israeli-South African test of a low-yield fission bomb.

Further Reading (listed in reverse chronological order, just like a resume):

Do your own independent research. Search for the phrase "South Africa" and the keyword "Nuclear" at the Central Intelligence Agency’s Freedom of Information Act website. It’s not easy to use, but there are a lot of interesting, original documents to peruse in this online archive. Also great for people who don’t like reading a lot since the CIA has a thing for censoring text.
