where following a claim from a resident who fell down a pot - hole in the road , EXTRA lighting has been installed all around the site
Surely the solution is to fill in the hole - not light it upAt my static holiday home site (in the darkst Yorkshire Dales) everyone sensibly goes around at night with a torch/lantern. Whats happened to the principle of taking responsibility for yourself. Anyone who walks around at night in teh dark and falls down holes deserves to! (says me who fell 4 foot down the hole dug for my observatory pier, while gazing upwards - whoops! and it hurt - hey I could sue myself!)

Humm.  I don't know how to take a picture of it, but imagine mile after mile of refinerys, chemical plants, industrial sites, all lighted like daylight at night.  Imagine living more or less in the middle of that.Locally, it's not to bad.  I have one neighbor who leaves a "securiy light" on all night, but it's relatively easy to block. (And they are good neighbors. They would turn it off for a while if I asked.)  Other close lights are screened by trees and houses.In my case it's just something you have to live with, and try to get to a dark sky site when you can, and I do have one available year round. But it's a 2 hour drive.Hubert

In the summer I have a Driving Range about a mile to the East, fortunately there's a bit of a hill between us, So nothing as bad as what tonk has, And then in the winter I have 2 ski resorts a couple miles to the west, that are open until at least 2:00am, with a lot of lights shining on a lot of white shiny snow.

The only light pollution I have are the domes from town (west), and a city/town combination (south). They mainly stay within the 30° airmass unless there's excess moisture in the air. Guess I'm one of the lucky ones.

I'm not too bad here. I don't actually live in Oxford (the nearest City) but in a village 8 miles to the south.

I have mild light pollution (ZNELM = 5.8 on darkest nights) with the local towns causing light domes to the North, East and South-East, the worst of which, to the North is approx. 50 degrees in extent - though like Carol said they get worse with certain atmospheric conditions, especially clouds!!!

Just taken some photos for ya. (Not very good, due to rubbish camera and operator!! )This is the view from my backgarden (where I do most observing) looking to the North over the houses [and a couple of tall trees].
Surprise, surprise  ...it's cloudy tonight!!

And this is the view to the South East, where the light pollution from another town is slightly less.
(It looks brighter though because you can see closer to the horizon than in the other photo)

Living in central/eastern CT, most of the western sky is washed out to 40-45º from the horizon, thanks to Hartford nearby to the west, and New York city to the southwest. Otherwise, the skies are consistently magnitude 6ish everywhere else (on moonless, transparent nights, of course).

I took a couple of photos, but they actually came out pretty dark - so I am lucky.  I live in an urban neighborhood that has plenty of street lights, but due to a fortunate and random combination of obstructions, almost all of the direct glare is blocked.  I have a very dark corner of the yard that is shielded by trees, 8-foot privacy fence, the house, and the garage.  But the price I pay for this localized darkness, is that my view of the north is almost completely blocked up to about 60-degrees or more, and my view to the west is 90% obstructed until you reach the zenith.  I can observe to the east with a neighbor's house obstructing the view up to about 30 degrees.  I have a good view due south, which is the darkest, but the garage blocks everything below 25 degrees or so.

The western sky is the direction where most of the development is taking place and towards the most populous part of the city.  The entire western sky is a bright aquamarine color up to about 70 or 75 degrees.  The east is a somewhat darker aquamarine up to about 40 or 45 degrees.  The south and the zenith are a moderate navy blue color with a ZNELM of about 4.9 or 5.0 on very good nights with low humidity and low light scatter.  On most nights the ZNELM is about 4.4 or 4.5

I would estimate the Bortle class here on the better nights is about 7 (red).

Clear skies,

MikeG

I have zero light pollution.  One neighbor has a motion-sensor light on their approach to their gate, but it goes off in a few minutes.  Their house lights are hidden behind large trees.No other lights around, except a couple yard lights quite some distance away, maybe 8-10 miles.Carol
