Good to know

  • A pass can be seen when the station is still in sunlight while the sky over Alcalá de Henares is dark, in the hours after sunset or before dawn. It looks like a bright, steady star crossing the sky in a few minutes.
  • The times are predicted from the latest published orbital elements, not observed, and cloud isn’t taken into account.
  • Passes are counted from 10° above the horizon, where buildings and haze stop hiding them.
