1.  Light pollution has caused, and is causing, great damage to astronomy. Some major observatories have had to curtail their activities drastically, and this means that students have insufficient observing opportunities.

  2.  Current guidelines do need to be strengthened, to ensure that strong lights are not installed close to observatories. The aim should be to insist on suitably screened lights, which shine down, not up.

  3.  Some authorities are co-operating well, but others are not.

  4.  Yes, measurements can be made and an acceptable level agreed.

  5.  Controls on public lighting are needed. Of course we must have good ground lighting, since law and order has largely broken down in some areas, but screening is the answer.

  6.  Amateur astronomers are badly handicapped by light pollution—and the amateur of today is the professional researcher of tomorrow!
