Blue sky

Today we have got a perfect blue sky above us.

Puma

Puma helicopter patrolling M25. One over the house every 20 minutes or so. A show of strength for the Olympics closing ceremony.

Red Kite

12.10 BST. Red kite circling house being mobbed by gulls.

Perseids

Every August the earth passes through the debris trail of comet Swift-Tuttle. Around the 11th to 12th of the month this produces the Perseid meteor shower. Under ideal viewing conditions it is possible to see upto 200 meteors per hour. Last night I observed from 23.00 to 02.00 BST. I saw 2 perseids. However I did see one sporadic meteor that was spectacular. A sporadic is a meteor that originates from a different part of the sky to the shower and does not come from the debris cloud.
