Whats your light pollution level


Pluto the Snowman

Recommended Posts

According to this map:

http://www.avex-asso.org/dossiers/pl/uk/index.html

I live in an orange zone. The zone colours are explained here about halfway down: http://www.avex-asso.org/dossiers/wordpress/?page_id=127

It explains why the Andromeda galaxy is very faint in my binos even tho its classed as a naked eye object. Fortunately for me there is plenty of green (which I hope is actually the "Black: green by texture transparency" rating) just 15-20 mins drive from where I live. Im so tempted to take my binos out there to see what Im missing next time I get a chance.

There must be some variation in orange zones. I'm in one according to that map but I can see M31, the double cluster in Perseus and a fair chunk of the Milky Way with my naked eyes on a decent night here. Things are nowhere near so good towards my NE and SW horizons though due to the Bristol and Newport "glows" so it depends on the part of the sky I'm looking at.

I would say so John, it looks like I am in an orange zone, but never see the MW from here or the DC. I occasionally glimpse M31 with averted vision. Have some sympathy with us 'townies' when you mention LP :)

Actually I was guessing because the map was not working properly on my iPad. I suspect I am either red or white. Inside the M25, just south of Heathrow and the M3..... :(

My understanding is that the map is at last partially based on modelling that may not be accurate.  For example whilst I am in an area where there is no light pollution according to the map, the nearest village has a turquoise glow around it.  Yet if you wanted to count all the houses in that village you'd not even need to take both your socks off, which is probably just as well as there are no streetlights to see by to put them back on.  All of which means that it's really not at all bad and once the locals have gone to bed it's as dark as anywhere.

Well after last night I need to amend this. Stunningly clear night, the darkest I have measured at home, mag 19.4. The Milky Way was still not visible, but both M31 and the DC were nice and clear naked eye.

I Know the feeling im few miles south from heathrow get a nice orange ball of light that stretches at least 35-40degrees up on a bad night also M25 don't help matters looking west

I'm on the border of a yellow/orange/green zone but suffer with the big orange glow from the south coast towns and Gatwick/Crawley10miles away.

I can see the MW as a washed out cloud and brighter dsos are visible.

I remember when I was at school, back 50 years a go the LP here was non existent, skies were black.

I think these kind of LP maps are a bit like weather forecasts and watching to see if it will be cloudy. The LP where i live is (what i think) minimal. Within 2 mins drive or 5 min walk from my house (in opposite directions) i can either be:

A/ On the main street of my local town with its street lights and pubs,restaurants and take-a-ways (way too many of those, but it is a University town)

Or 

B/ Slap bang in the middle of open countryside for miles and miles around with no street lights and only cows and other assorted types of animals to keep me company.

My back garden is in the middle but i'm closer with regards to LP to being in the rural setting. Some night though the skies above my house are aglow with the LP from the town spilling over and reaching me. On these nights though there tends to be a lot of moisture in the air and conditions are not ideal for observing.

I consider myself very lucky compared to others. I cant imagine what it would be like not to be able to see M31,M42 or M45 with the naked eye.
