Charts for August 13 to September 10 2010
No. 154
The
Summer Triangle of Vega, Deneb and Altair stands high above as the sky
darkens on August evenings. The deep yellow of Arcturus is sinking
towards the western horizon, and the stars of the Plough dip low in the
north-west. Antares still glints in the south-west for those below
latitude 50 degrees north, while in the south-east lonely Fomalhaut
climbs above the horizon in its barren part of the sky. In the east
rises the Square of Pegasus, followed by the stars of Andromeda.
Capella is above the northern horizon for observers north of latitude 40

Light Pollution
Recently
The House of Common's
Science
and Technology Committee reported on "LIGHT POLLUTION AND ASTRONOMY",
but
when Tom Harris MP of the Select Committee asked a question in the
house
about light pollution on Oct 22 2003, it was treated less than
seriously
by many present. Please write to Rt.Hon. A. Blair MP, Prime Minister,
10
Downing Street, London.
