Automatic summary, not yet reviewed

  1. The law limits outdoor lighting, radio transmitters, and industries or activities that pollute the atmosphere on the island of La Palma, so they do not harm the sky quality of the observatories.
  2. Outdoor lights must avoid emitting light above the horizon, except those needed for air navigation, and must disturb astronomical observations as little as possible.
  3. Above 1,500 meters of altitude, polluting industries or activities that exceed the set limits cannot be installed. The Instituto de Astrofísica de Canarias must also issue a report before licenses are granted for outdoor lighting, transmitters over 250 watts, and high-altitude installations.
  4. The law also protects the Tenerife observatories against new installations that degrade the sky, except for outdoor lighting. The State pays the local councils of La Palma for adapting existing public lighting.

Who it affects

  • Residents and businesses of La Palma: They must limit their outdoor lighting so it does not disturb the observatories.
  • Polluting industries and activities: They cannot be installed above 1,500 meters if they exceed pollution limits, and they need a report from the Institute for their license.
  • Radio transmitters: Those over 250 watts need a prior report from the Instituto de Astrofísica de Canarias.
