ISS and Hubble cross same region of the sky.

The ISS - International Space Station and HST - Hubble Space Telescope cross the same region of the sky a few minutes apart.
It is a rare observation, as Hubble is significantly smaller, body and solar panels, than the ISS, which means lower reflection power or magnitude.
In addition to this fact, Hubble's orbit is usually just a few degrees above the horizon, a region of the sky with greater light pollution, which makes its observation even more difficult.
In the foreground, the open pit of the old São Domingos copper mine deactivated in 1964.
