A horrible start to the day as torrential rain fell in London. Despite this there was a lot of activity in the Garden. A group of Common swifts remain in the area – I wonder if they will stay in the area and nest this year. The highlight of the day occurred at 1725 as looking out of my study window I saw a large bird approaching from the north. As it drew closer I could see it was a Common Buzzard, a first ever sighting for the patch. The Bird continued to fly South over the garden and over the Tarn.

Today’s pictures are of the dumbbell nebula (M27/NGC6853). It is a planetary nebula found in the constellation Velpecula. Like most nebula it consists of dust and gas surrounding a central core. In the case of the dumbbell nebula there is a central star, a white dwarf -the largest known of its kind. The nebula was first described by Charles Messier in 1764. It is 1200 to 1400 light years from Earth, but its brightness it means it is easily visible with binoculars or a small telescope.

Planetary nebulae are formed in the dying stages of a star when the core fusion reactions decline to the extent that the star’s structure cannot be supported – gravity forces the outer part of the star to collapse inwards, causing the inner part to condense and heat up. The intense build up of pressure and radiation causes the outer shell to ‘explode’ and be driven away. The intense stellar wind causes the surrounding gases to ionize in bright colours.

At home over the weekend which gave me the opportunity to watch the garden and check on its resident species. The highlight was the appearance on Saturday afternoon of a party of eight Common Swift which appeared over the garden for about 20 minutes. This was the first time that we had seen them on the patch this year.

Monitor 33

Monitor 33 is a First World War gunship, built to bombard coastal positions from the sea. She is one of the few such vessels surviving. One interesting aspect is her camouflage, which is not designed to render her ‘invisible’ but specifically to confuse the range finding systems of the day so that land and sea-based artillery would find it difficult to fix her and accurately direct directly there gunfire.
Monitor 33 is currently on display at the Portsmouth historic dockyard
