Topic: Light Pollution where you live Posted: September 06 2007 at 13:01 |
Light Pollution: Wasted light from city and outdoor lights that makes it hard to see the stars at night.

It's quite high here, and it makes me so angry. I hate illuminated billboards and only grudgingly tolerate street lights. :(

I voted "low" it's pretty good here, only spoiled by the fact that I have just moved from a place that was INCREDIBLY good, when I took the kids to Greenwich observatory a few years ago, they were pleased that when we were registering for the junior astronomers club the astronomer bloke who gave the lecture heard us say where we lived and got all excited said it was one of the best places in england to star watch!
Having said that I found the stars pretty darn impressive in Central America, and also in the Orkney Isles (accompanied on a few nights by the Northern Lights which was so damn cool can't explain!)
All in all though I think where we are now is pretty good.

Maybe those "brightest stars" are the planets ;) I know, some urban areas are horrible!

I live in LA so when it's at least a little cloudy/misty it reflects the enormous amounts of light coming from this hell, so of course no stars. When the sky is clear, stars are visible though mostly whatever's more or less directly above, the rest gets lost in the cloud of pollution illuminated by the city.

The light pollution in very low where I am living at the moment. It is in the smallest capital city (hence less light pollution), many nights if it is not cloudy, you can see wealth of stars. It is even clearer at my parents place, their is 200km of bush behind our house.

I live in a small village with no street lighting, but there are several major towns in a 10 mile radius all around us so I have a permanent orange glow to the north-west and east. Here I can see most stars of Magnitude 5 and brighter, but the Milky Way is pretty illusive.
If you live in the northern hemisphere a good way to guage the level of light polution is to locate Usra Minor (The Little Bear - it's the constelation with the Pole Star in it's tail) and count the number of stars you can see.
Even in a big city you should be able to see the 3 "big" stars in the drawing above but if you can see all 7 then the level of light polution you are experiencing is pretty low.

another way to explain the choices (thanks darkdean).
If you're quite in the north: _None: little dipper constellation easy to see. _Low: You can see the constellation, but the fainter stars need some staring and good eyesight. _Moderate: you can see Polaris (north star) and the other 2 bright stars, but not the rest _High: you can see the north star, but not easily _Very High: You can't see a thing.
if your latitude is more in the 15-30 Range _None: You can see the whole constellation _Low: You can see the whole constellation but the faint stars are barely seen _Moderate: You can see polaris and one other bright star, the 3rd brightest : maybe _High: you can 'barely' see polaris _Very High: nothing
or in a more technical way: Limiting Magnitures in order from none to very high: _None: 6.0 _Low: 5.0 _Moderate: 4.0 _High: 2.5 _ Very High: 1.5 or less

Very High. I can barely see the big dipper. One of the few disappointing things about philly

Only the brightes ones I think, and the Moon.
Outher parts of the city like the Buda Mountains are better, from there you can see pretty much.

It's not too bad here, but I used to Live in Chicago. Every once in a while, I may have been able to see one or two stars. I remember coing back to Michigan for a visit. I looked up on a clear, dark night. I thought, oh yeah, that's right, stars.

As a rule of thumb, I would guess that anybody with an internet connection is in a location with at least some amount of light pollution. I doubt "None" will show up very often in this poll.
