Demonstrations take place on Mondays and Thursdays from 19:00 to 21:00, if the sky is clear. On these evenings, if the stars are out, come and observe them closer at Raiņa bulvāris 19, Riga, taking the stairs to the roof. Apart from such interesting stars as Polar Star, Sirius, double stars, through the modern telescope with a 20 cm diameter objective you can also see the Moon, planets, star clusters, nebulas, and galaxies. In December, the particular attention will be dedicated to the Geminids Meteor Shower, while in January the viewers will be able to observe a lunar eclipse. There is also a possibility to see a bright comet.
The observation season lasts until March, when, following the Daylight Saving Time, Latvia reverts to Summer Time and the sky becomes lighter. The entrance fee for adults is 2 euro, for students, seniors and invalids – 1 euro. The University of Latvia students can enter free of charge. The Astronomical Tower is deliberately designed for the building in Raiņa bulvāris 19, which was constructed during 1866–1869. The telescope of the 19th century was used for scientific observations. At the first half of the 20th century, students carried out their practical work here, and since 1986 the Astronomical Tower works as a public observatory.
