9.  Dwarf planet Pluto (V ~ 14) occulted a star (V ~ 14.4).  SOFIA met the shadow of Pluto in mid-Pacific. =>  HIPO (Lowell Obs.) and FDC (DSI) instruments observed the occultation simultaneously. SOFIA observations of a stellar occultation by Pluto on July 23, 2011 Image sequence from the Fast Diagnostic Camera (FDC) FDC Pluto (circled) is 13 arcsec from the star 200 minutes before the occultation Just before occultation: Pluto and star merged, combined light During occultation: Pluto and star merged, only Pluto light seen After occultation: Pluto and star merged, combined light
