For the first time three gravitational wave detectors have recorded the same event. The detection was made by both LIGO and Advanced Virgo (which has just recently begun collecting data for the first time). From the news release:

The LIGO Scientific Collaboration and the Virgo collaboration report the first joint detection of gravitational waves with both the LIGO and Virgo detectors. This is the fourth announced detection of a binary black hole system and the first significant gravitational-wave signal recorded by the Virgo detector, and highlights the scientific potential of a three-detector network of gravitational-wave detectors.

The three-detector observation was made on August 14, 2017 at 10:30:43 UTC. The two Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, and funded by the National Science Foundation (NSF), and the Virgo detector, located near Pisa, Italy, detected a transient gravitational-wave signal produced by the coalescence of two stellar mass black holes.

A paper about the event, known as GW170814, has been accepted for publication in the journal Physical Review Letters.

    Look at the Virgo page - when did Virgo *announce* the result?

    Clue - Sept 27 was a day back, not a month back (and greetings to my readers on the Pacific for whom it's still the 27th)

    Sure, they dropped hints that they had some interesting looking candidates at the start of this month, but, in their own words, "it will require time to establish the level of confidence needed to bring any results to the scientific community and the greater public. We will let you know as soon we have information ready to share."

    Do you want press departments pushing upon the world half-baked false positives, or do you want the scientists to be doing science correctly?

    I want eds that are not pressured by alt-right leaning birds of carrion. That is all I want. As for this, point taken. Only recently announced, for all three. But the one in Pisa, I suspect, was leaning, slightly.l
