ALMA image of the field towards J1407. The location of the star J1407 in 2017 is shown asa white square, and the white triangle gives the location at the time of the eclipse in 2007. The white ring indicates the expected location for an object travelling at 35 km s⁻¹ between the two epochs (assuming that the object is co-distant with J1407); the dotted lines represent the 1σ uncertainties. The detected ALMA source is at a position angle of approximately 95 degrees. The ALMA beam is shown in the lower left corner.
