Observatorio J87 La Cañada
Latitude 40º 36.3' N, longitude 04º 29.5' W, altitude 1387 m
(La Cañada Observatory)

Astronomical observatory located in La Cañada, Ávila, Spain, founded by Juan Lacruz in 2002.

The observatory joined the International Astronomical Union (IAU) sending the first astrometric observations in the summer of 2002 to the Minor Planet Center (MPC) and was assigned the observatory code J87.

The J87 Observatory has been credited the discovery of 76 numbered asteroids up to Sept. 2024

Since March 2022 joined the international asteroid warning network IAWN for an international response to a potential NEO impact threat.

In 2023 started a survey of galaxies.

We track the ambiental evolution keeping a digital archive of the wild life and atmospheric phenomena.
