Juno’s close approach to the Earth
As noted in BAA e-bulletin 765 the Juno spacecraft flew within 560km of the Earth’s surface last night on its way to Jupiter. It was imaged by a number of observers including Peter Birtwhistle and Nick James:

Astrometry from these images was processed by Bill Gray and this shows that the spacecraft is safely on its way to Jupiter: http://www.projectpluto.com/temp/juno.htm
Much more detailed radio tracking data was obtained by the Deep Space tracking stations of NASA and ESA.
