Summer Moon

Today is the 21st June which makes it the longest day of the year. This is known as the summer solstice - which actually occured at 06:36 UT (07:36 BST) this morning - and is the time when the Sun gets as far north as it will get during the course of the year.

Tomorrow sees full moon; the Moon will be on the opposite side of the sky to the Sun and therefore fully illuminated. With the Sun so high during the day, the full moon will be very low during the night. In fact, according to NASA's Exploring the Universe, it is the lowest full moon since June 1987. This gives you a good chance to see the famous 'Moon illusion' that makes the Moon look bigger when near the horizon.
