Pluto and the City of Flagstaff, Arizona, are forever linked in history. On February 18, 1930, astronomer Clyde Tombaugh discovered Pluto at Lowell Observatory in Flagstaff, using a blink comparator and photographic plates. The New Horizons probe reached the Pluto system 85 years later last July, imaging Pluto, its largest moon Charon, and the other small moons.

Pluto has since been downgraded to “dwarf planet” status. Nonetheless, 2015 was designated the "Year of Pluto." To celebrate, the members of the Northern Arizona DX Association (NADXA) will mount special event station W7P starting at 0000 UTC on December 5 and concluding at 2400 UTC on December 13, from Lowell Observatory. W7P operators will be on the air from inside the Pluto discovery telescope dome, as well as from club members’ homes.

Operation will be on SSB and CW. Special guest operator Doug Tombaugh, N3PDT, the nephew of Clyde Tombaugh, will operate for a few days during the early part of the special event period. QSLs and a certificate are available.
