Nice picture indeed..
This summer have been, at least in Finland, rich on noctilucent clouds.
At the moment there have been observed about 30 displays by Finnish
network. The most of displays have been rather faint, but some
brilliant shows have seen.
In addition of 16/17 Jul, which Paul have photographed, also following
night have been bright and wide: 27/28 Jun, 12/13 Jul, 13/14 Jul,
21/22 Jul and 25/26 Jul.
