New gravitational-wave candidate from last night!
If S251006dd turns out to be real / of astrophysical origin, it came from a coalescence of two black holes at a distance of around 2.3 billion light-years.

The chirp mass is between 5.5 and 11 solar masses. This means, if both black holes have the same mass, they each weigh between 6 and 13 solar masses.
The sky position could be determined to an area of about 100 square degrees.
