We report the discovery , via the microlensing method , of a new very-low-mass binary system .
By combining measurements from Earth and from the Spitzer telescope in Earth-trailing orbit , we are able to measure the microlensing parallax of the event , and find that the lens likely consists of an ( 12.0 \pm 0.6 ) M _ { J } + ( 15.7 \pm 1.5 ) M _ { J } super-Jupiter / brown-dwarf pair .
The binary is located at a distance of ( 3.08 \pm 0.18 ) kpc in the Galactic Plane , and the components have a projected separation of ( 0.43 \pm 0.03 ) AU .

Two alternative solutions with much lower likelihoods are also discussed , an 8- and 6- M _ { J } model and a 90- and 70- M _ { J } model .
Although disfavored at the 3- \sigma and 5- \sigma levels , these alternatives can not be rejected entirely .
We show how the more-massive of these models could be tested with future direct imaging .
