Odessa-Mayaki observatory (583) has discovered new asteroid 2017 BC94 and re-discovered 2017 AB8 asteroid

With help of free version of the CoLiTec software 2016 – Summer (1.6.6.1) the observing station Mayaki (583 – Odessa-Mayaki) of Astronomical observatory of I.I. Mechnikov Odessa National University in early 2017 has discovered new asteroid 2017 BC94 and re-discovered 2017 AB8 asteroid.

The 2014 OD380 asteroid was firstly observed by Pan-STARRS 1 observatory, Haleakala in 2014. Afterwards there where several successful unrelated observations of this asteroid in 2015, after each of which the object was lost due to the insufficient number and period of observation for the calculation of search ephemeris.

On January 3/4, 2017 by two staff researchers of Astronomical observatory of I.I.Mechnikov Odessa National University V.I. Kashuba and V.V.Troyankyi discovered an unknown object. Using these observations, the orbital elements of object was determined and object was re-found again on January 26, 2017. The IAU Minor Planets Center was named this object 2017 AB8 (2014 OD380).

CoLiTec published article in Open European Journal on Variable Stars

CoLiTec Team published new article “FrameSmooth software – new tool for the calibration of astronomical images” in «Open European Journal on Variable Stars», which is included in the science database of NASA – Astrophysics Data System (ADS).

The traditional procedure of image calibration in differential photometry is based on correction for dark-frame and flat-field. This approach don’t remove big scale non-uniformities in the detector illumination caused by Moonlight or other scattered light. This can be corrected by mathematical methods. Ukrainian developers of CoLiTec software use inverse median filter for astrometric tasks. We have tested the possibility to use it for photometry also. The answer is generally positive. There is a chance to skip the flat-field calibration in some cases. We present the FrameSmooth software which performs different image calibration procedures and also able to operate in fully automatic mode.

Sayan Solar Observatory (C48) has discovered two new asteroids – 2016 SX34 and 2016 SZ34

With help of free beta-version of the CoLiTec software 2016 – Summer (1.6.6.1) Sayan Solar Observatory (C48) of Institute of Solar-Terrestrial Physics during the short period of time has discovered two new asteroids – 2016 SX34 and 2016 SZ34. Also, temporary designations of three asteroids have been changed according to the observations of C48. About 30 objects that are not present in catalogue were identified as moved objects.

CoLiTec published article in Odessa Astronomical Publications

CoLiTec Team published new article “Virtual observatory and CoLiTec software: modules, features, methods” in «Odessa Astronomical Publications» journal, which is included in the science database of NASA – Astrophysics Data System (ADS).

We describe complex processing system created by the CoLiTec project. This system includes features, user-friendly tools for processing control, results reviewing, integration with online catalogs and a lot of different computational modules that are based on the developed methods. Some of them are described in the article.

The main directions of the CoLiTec software development are the Virtual Observatory, software for automated asteroids and comets detection and software for brightness equalization.

The CoLiTec software is widely used in a number of observatories in the CIS. It has been used in about 700 000 observations, during which 1560 asteroids, including 5 NEO, 21 Trojan asteroids of Jupiter, 1 Centaur and four comets were discovered.

The Štefánik Observatory is located in the very heart of Prague, in Petřín’s parks at the Hunger Wall which was built during the reign of Charles IV in the 14th century. The observatory was opened on June 24th, 1928. In the middle of the 70s, a full-scale reconstruction gave the building its current appearance and it was reopened for the public in 1976. Since 1979, the Štefánik observatory has been a part of the Observatory and Planetarium of Prague.

Pavol Dubovský, astronomer from Vihorlat Observatory and Astronomical Observatory on Kolonica Saddle, Slovakia, presented communication with the following title: «FrameSmooth software – new tool for the calibration of astronomical images». The team of authors is international (Slovakia-Ukraine). Ukraine was represented by Kharkiv National University of Radio Electronics (Sergii Khlamov, Artem Pohorelov, Olexandr Briukhovetskyi, Vladimir Vlasenko) and Uzhgorod National University (Vadym Savanevych).
