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!

• The Teapot is a well-known asterism (an easily recognized pattern of stars) within the constellation Sagittarius.
  o
• Although it isn’t an official constellation itself, it’s one of the easiest star patterns to spot in the summer sky.
  o

• Antares is famous because it is one of the biggest and brightest stars you can see in the night sky.
  o
• The Moon helps you easily find the Scorpius constellation.
  o
• It’s a nice event for stargazing with the naked eye.
  o

• Spica is one of the brightest stars in the night sky.
  o
• It is actually not just one star, but two stars that orbit each other.
  o
• These two stars are very hot and shine with a strong blue-white light.
  o
• Even though it looks like a single star to our eyes, it is about 250 light-years away from Earth.
  o

• Lunar X and Lunar V
  Sunlight catches rims at lunar first quarter to create the bright V and X shapes.

• Best viewing time in the UK
  The phenomenon occurs in the late evening for British Summer Time (BST).
