36614 Saltis was discovered at the Stockholm Observatory. The asteroid was named after the nickname of the observatory's location, Saltsjöbaden, by its discoverer Alexis Brandeker in 2003. 4043 Perolof is named after a director of the Stockholm Observatory, Per Olof Lindblad. Stockholm Observatory at Saltsjöbaden It was common all over Europe for really old observatories to build in a new site, fortunately the old observatory was not torn down has happened in many cases. Then as the utility of the new sites also waned, the old site was revitalized. This happened similarly in England, where the Greenwich Observatory was moved to a new site in Sussex with new buildings, but then back to the old site again. One issue was the increased crowding in the cities, and also astronomy was growing more focused on data from space in the late 20th century. In any case the 40-inch (102 cm) reflector was one of the larger telescopes in the whole world for 1931, and is still a large and popular telescopes size even in the 21st century. Instruments Some first instruments for the observatory in the 1750s were two refractors and a small quadrant. Throughout the late 1700s the collection was increased, including a refractor from Dollond and various clocks. The clocks would be set by a device known as a transit instrument. Other activities at that time included trying determine distances in the solar system, observing comets, and observations of the Mira (aka Omicron Ceti). Of note the output of this star was recorded for thirty years by the observatory. Later instruments by the 19th century include a 7-inch Repsold refractor on an equatorial mount, which was noted to be used at the observatory for parallax observations of bright stars in 1884 edition of Encyclopædia Britannica. Some of the new instruments at Saltsjöbaden: 40 inch (102 cm) reflecting telescope from Grubb, built in 1931.
