Ursa Astronomical Association (Finnish: Tähtitieteellinen yhdistys Ursa ry) is the largest astronomical association in Finland. Ursa was founded on 2 November 1921. Founding members include a renowned Finnish astronomer Yrjö Väisälä. In 1926 Ursa established the Ursa Observatory in Kaivopuisto district of Helsinki. In 2007 the Tähtikallio Observatory & Education Center was established in Artjärvi, its current equipment includes an Astrofox 36" Folded Newtonian Open tube telescope, an Alluna 16" Ritchey-Chrétien telescope, a Meade 16" LX200GPS Schmidt-Cassegrain telescope, a Sky-Watcher ED 120mm refractor telescope fitted with a Baader AstroSolar Solar Filter and a piggybacked Coronado SolarMax 40 H-Alpha telescope. Ursa's primary functions include advancing amateur astronomy and astronomical education. They have published a magazine Tähdet ja avaruus since 1971 and have provided awards to exceptional members of amateur astronomy for significant astronomical observations since 1988. Anyone can join Ursa for an annual fee.
