At the same moment, winter begins in the southern hemisphere.
Happy Solstice!
Today, summer began in Poland with a sunrise display of noctilucent clouds. "They were so bright and beautiful," says Marcin Makowski who sends this photo from the city of Szubin:
It is a curious fact that noctilucent clouds, which are made of ice crystals, appear most often during the warm months of summer. In the last week alone, the clouds have put on a show over Europe that veteran observers say has been the best in years. Now that summer is here, the show can really begin. Northern sky watchers should be alert for electric blue.
