Due to Covid-19 social distancing restrictions, a limit has been set on the number of visitors to the observatory. There will be room for 5 seated guests at a time. In special cases, there will be space for 4 extra guests in the adjacent room. The observatory can therefore receive groups of a maximum of 9 people at a time. On Mondays, when the observatory is open without pre-booking, a display system will be in place below the stairs to show whether there is room in the observatory.
The observatory also has an interesting minor collection of instruments as well as building stones from Hven. The Sirius Observatory was founded in 1923 by electrician Møller Nicholaisen. He was an active amateur astronomer, which, however, did not prevent him from making internationally acknowledged observations.
The observatory is open Monday evening 20–22 during the months of February, March, October and November, provided it's a starry night.
During week 42 and week 7, the observatory is sometimes closed for holidays, but you are welcome to send an email or a text message to check opening hours. If you are a group (school class, scouting group or other interested group) you are also welcome to call or write and make a special appointment at an agreed time. There is free admission.
