Orion Star Count Survey 2011

Posted by XTSee on 1st February , 2011

Two nights this week I have participated in the Campaign to Protect Rural England’s Star Count Survey for 2011.

You can take part by counting as many stars as possible in the constellation Orion, in an area bounded by the four main corner stars, go here for instructions and to take part (you must do it this week Monday 31st Jan 2011 to Sun 6th Feb)…..


The survey is intended to highlight the problem of urban and rural street lighting causing light pollution, and to help map out light and dark parts of the country.

Excluding the four corner stars, people in towns may only see 6 to 10 with the naked eye, no telescopes, or binos allowed!

Yesterday, in the shadows of my garden in Corby Glen, Grantham, Lincs, on the edge of the village, after about 20 minutes allowing my eyes to dark adapt, and using “averted vision” to use the sensitive monochrome region of my eyes, I was able to make out 23 stars. The sky was clear, but a bit hazy, with some light wispy clouds. Tonight I repeated the test, and much clearer, I was able to make out 31 stars.

How well did you do?
