The Kleť Observatory is a research institution belonging to few natural science centers of Southern Bohemia in the Czech Republic, supported by the South Bohemian Region and various grants. The observatory is situated south of the top of Klet mountain (at altitude of 1070 m), southwest from the town of České Budějovice. There are one hundred and fifty clear nights per year with a good astronomical seeing on the average, as shows data from photographic observations of minor planets and comets since 1968. The Headquarter of Kleť Observatory is located at the Observatory and Planetarium in České Budějovice.
Competences and capabilities
Ground segment for Space Safety Programme -Near Earth Objects (NEO):
- Confirmatory observations of newly discovered NEO candidates, especially fainter and fast moving objects as well as NEO candidates having larger ephemeris uncertainty (both lim. mag. about V = 22 mag. and larger FOV are benefits of 1-m KLENOT Telescope)
- Recoveries of NEOs in the second opposition
- Follow-up astrometry of poorly observed
- NEOs - Virtual ImpactorsĒ and PHAs, target of space missions or radar targets
- Cometary features. Analysis of possible cometary activity of newly discovered bodies.
- Search for new asteroids as a by-product.- Educational and public outreach activities in related field (asteroid hazard, space safety)

Space Related Equipment, Labs & Certificates
- 1.06-m KLENOT telescope with 4-lenses corrector to obtain a plane FOV 0.63 x 0.63 degrees, computer controlled equatoreal mount, equipped with CCD camera
- FLI ProLine 230. Limiting magnitude of mV=22.0mag.
- The hardware and software equipment for KLENOT project consists of local network, servers and workstations for operating CCD camera, instantaneous visual detection, image processing, data reduction, identification of moving objects, ephemeris calculations and orbit computations. The Klet Software Package has been continually upgraded.
- In order to increase tracking accuracy of the KLENOT telescope mount the main gearbox was upgraded. New feature: HW + SW system for sidereal off-set tracking was installed in order to increase limiting magnitude of observed moving objects.
