Taivaanvahti can also be used in Swedish and English

24.9. completed maintenance break brought new features to Taivaanvahti and opened the system in Swedish (Himlakollen) and in English (Skywarden) for users from Northern Europe. We hope that the changes will make the site easier to use for the Swedish-speaking minority and enable new forms of Nordic co-operation. The change would not have been possible without the support of the Svenska Kulturfonden and the effort that individual enthusiasts put into the translations. Warm thanks to everyone involved in the project!

A few days earlier, Vesa Toropainen photographed a similar view while soaring down above the clouds.
