Crni Vrh Observatory

MPC observatory code 106
Longitude: 14^o 04' 16" East; Latitude: 45^o 56' 45" North; Altitude: 726 m
First Published November 10, 1995

Crni Vrh Observatory is operated by a group of dedicated observers. We run a Comet and Asteroid Search Program named PIKA after a Slovene acronym. For that purpose, we designed and built a 0.6-m, f/3.3 Cichocki telescope (named after B. Cichocki). It is custom made, advanced technology, wide-field imaging system, designed for sky survey applications. Since 2004, it operates as a remote robotic telescope. It nightly scans the sky and returns new discoveries of small Solar System bodies, which sometimes threaten our home planet Earth. Recent software upgrade enable us also discovery of distant cosmic explosions such as supernovae, Gamma Ray Bursts and variable stars. See also our 2 minute video presentation and recent updates of the PIKA project.
