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.

	Comet C/2022 QE78 (ATLAS) Unfiltered false color image of comet C/2022 QE78 (ATLAS), obtained on 2025 Dec. 30 (2h03-2h22UT) with 60-cm, f/3.3 Deltagraph telescope and CMO. Exposure time was 15 minutes (15x60 seconds). Image scale is 1.46 arc sec/pixel. Copyright © 2025 by H. Mikuz, Crni Vrh Observatory.

	Comet C/2025 K1 (ATLAS) Image of comet C/2025 K1 (ATLAS), obtained on 2025 Dec. 13 (22h16-22h37UT) with 60-cm, f/3.3 Deltagraph telescope and CMO. After the fragmentation in early November 2025, at least two components are visible on this frame. Exposure time was 15 minutes (30 x 30 seconds). Image scale is 1.17 arc sec/pixel.

	Periodic Comet 24P/Schaumasse Unfiltered false color image of periodic comet 24P/Schaumasse, obtained on 2025 Dec. 14 (4h32-4h50UT) with 60-cm, f/3.3 Deltagraph telescope and CMO. Exposure time was 15 minutes (15x60 seconds). Image scale is 1.17 arc sec/pixel. Copyright © 2025 by H. Mikuz, Crni Vrh Observatory.

	Periodic Comet 240P/NEAT Unfiltered false color image of periodic comet 240P/NEAT, together with fragment 240P-B, obtained on 2025 Dec. 13 (21h30-21h49UT) with 60-cm, f/3.3 Deltagraph telescope and CMO. Exposure time was 15 minutes (15x60 seconds). Image scale is 1.86 arc sec/pixel. Copyright © 2025 by H. Mikuz, Crni Vrh Observatory.
