Noctilucent clouds

• The best time to see noctilucent clouds is during this month ~ July, although they can sometimes be seen from late May to early August.
  o
• They are easiest to spot on clear evenings or early mornings in the northern sky after sunset or before sunrise.
  o
• They are made of tiny ice crystals and glow with a beautiful blue-white colour because they are still lit by the Sun after it has set.
  o
• You can sometimes see them on summer nights, low in the northern sky.
  Noctilucent clouds are the highest clouds on Earth.
  o
• They look like shiny, wavy ribbons and are one of nature’s most amazing sights!
