The traditional Cygnus -summer meeting of Finnish amateur astronomers was organized in Mäntsälä, Southern Finland. The event place was a camping site of the local Parish, called Leiriniemi. The place is located in the shores of a small lake called Keravanjärvi. The number of participants was about 120, which has been quite typical number during recent years.
The programme of the event consisted of lectures and workshops. Also a museum visit to home site museum of A.E. Nordenskiöld was included in programme. A.E. Nordenskiöld was an explorer, cartographer, mineralogist and geologist born and raised in Finland. Nordenskiöld was the first man to navigate through the Northeast passage. One of the most anticipated lectures was the 3rd part of the lecture series about the Moon race during the Cold war given by Hannu Määttänen. Other popular and interesting lectures were the lecture given by Arto Oksanen about the spectropolarimetry -observations of T Pyx in VLT, Chile and the lecture given by FMI researcher Harri Haukka about the Rosetta -comet exploration mission. Outside the formal programme, we were having sauna and having some good time with other fellow amateur astronomers and friends. The event ended in the excursion to Tähtikallio observatory in Artjärvi, only 60km from the event site.
Weather during the event was mostly warm and sunny, except few isolated showers. We also were able to observe some thunderstorms during the event. Noctilucent clouds were observed only during the first night of the event.
