The nights of October 30th and 31st are the best opportunity for studying this asteroid, which characteristics points that it could be an extinct comet.
The asteroid, with 400 meters wide, will be at about 480.000 km from Earth at its closest approach.
CARMENES, a spectrograph that will search for earth-like planets, is a unique instrument due to its stability, very high resolution and because it will observe at the same time in both the visible and infrared channels.
The infrared channel, developed at the Instituto de Astronfísica de Andalucía (IAA-CSIC), will be tomorrow placed in its final location, at the 3.5m Calar Alto Observatory telescope.
As it happened in 2014, Calar Alto Observatory has participated on the European Night of the researchers that took place last September 25, 2015.This year the participation consisted in two activities held in the Junta de Andalucía's Govern Delegation in Almería.
