Five planets shine in rare line-up
The planets appear in the sky 'like a string of pearls' until Monday.
Pretty, wispy clouds have been filling your reports today (Monday 4th July). These are a type of cirrus cloud, known as cirrus uncinus. The name is derived from Latin and means "curly hooks".
The clouds occur at very high altitudes, at a temperature of about −50 to −40C.
They are commonly known as mares' tails because of their likeness to horse tails. An old weather proverb goes, "Mares' tails and mackerel scales make lofty ships to carry low sails." Together, cirrus uncinus clouds and patchy altocumulus clouds often mean that rain is on its way.
Here's a selection of the gorgeous mares' tails you've been posting.
