This occultation will not only allow to improve Pluto’s orbit, but will also allow to follow the development of its thin atmosphere, when Pluto’s distance to the sun is increasing with the years. In the last two years Pluto’s atmosphere has further increased its density, as recently published in ApJL as can be find here. The upcoming occultation is a good chance, to continue the monitoring work.
