Approaching the longest day

As we approach the longest day of the year, here is the sun information today in Helsinki.

Sunrise 3:55.
Sunset 22:49.
Length of day 18 h 54 min.

In reality, the sky is light for most of the "night."

Here's a "darkness graph for 60N (Helsinki). Horizontal axis is time of day (midnight in the middle)) vertical axis is the day of year (January to December).

You can see that there is no real dark, just zones of twilight, until September.

Same for 70N and 30N

You can see why there are not too many active astronomers in Lapland during the summer...

And here you get tailor-made tables for most towns in Finland...
