Iceland to turn off street light to see stars

The story is a bit unclear if it's just this week or every Thursday. This isn't a good week since the moon is approaching full phase...

It was just that night only and only for a period of 30 minutes.

The moon doesn't disturb at all that day. On Thursday 28 Sept the Moon was
two days before first quarter .... true, this is "approaching full phase",
but otoh the Moon "approaches full phase" all the time from new to full...

Also: since Iceland is situated at a high latitude, not far south of
the arctic circle, and since it's (northern) fall, the Moon will set
at or very soon after sunset all the time from new to a few days
before full. It's actually hard to even see the Moon until it's
almost half at fall when the Moon is waxing (and equally hard at
spring when the Moon is waning). This is something you who live
farther south aren't used to, but it's nevertheless a fact at high
latitudes.

Actually, on Thursday 28 September the Moon is so far south in the sky
(declination -27 to -28 degrees) that the Moon is below the horizon
all the time as seen from Iceland -- it never rises there that day and
a few days afterwards.

Therefore, this Thursday is a perefectly good week for turning off the
light in cities - at least as far north as Iceland, Scandinavia and
Alaska. Further south (in e.g. Florida) another week would have been
better - but Florida isn't about to turn off its lights as far as I know.

The article only mentions this Thursday and says nothing about other
Thursdays - perhaps it's an experiment to see what the people think
about this idea.

I'd certainly LOVE to see Tokyo do this.

The idea is very nice. While it isn't going to suddenly sweep the
world, as people see the news stories, they might begin to realize that
they're missing something wonderful. Good publicity for dark skies.

Oh! My mistake. I was thinking the story was talking about this coming Thursday, Oct 5. Thanks Paul.
