May 1-version of CoLiTec (CLT) software

The project’s updating:

1. Optimization of interactions between independent blocks of CoLiTec software and supervisor program.

2. Thresholds’ coordinates for different stages of CoLiTec processing can be saved in a separate file.

3. CoLiTec software is upgraded with matching algorithm, invariant with respect to axes orientation of frame’s coordinates system and camera’s rotation angle. That permits wide fields’ matching (for example 8х8 degrees).

4. Results’ viewer is upgraded with a possibility to form tracks by an operator.

5. Updated algorithm of image correction by a high-pass filter for big size frames’ processing (7000х7000 pixels).

6. Introduction of new selective indications for observation’s scripts with frames’ addition 3+3+3 and 6+3.

7. Elaboration of results’ viewer (based on ViewCLT results’ viewer) for frames obtained by a fixed telescope and processed by APEXII software suite. The present software has not only tracks’ view function but stars’ centering of frames obtained by a fixed telescope.

8. Elaboration of a pilot version of software protection through hardware (electronic switch).

9. Fixed different bags.

Comet C/2010 X1 (Elenin) – the first comet discovered with CoLiTec (CLT) software

Discovery of the Comet Elenin C/2010 X1 (Elenin) with CoLiTec (CLT) application, attracted vivid interest of mass media.

The comet C/2010 X1 (Elenin) was discovered December 10, 2010 within the scope of asteroids’ program of Russian project ISON. The discovery was made by Leonid Elenin – scientific associate of Keldysh Institute of applied mathematics (RAS). More information on discovery, plus interview with discoverer («Газета.Ru») can be found through on-line media sources.

Leonid Elenin supports a news blog on (this blog has recently entered 20 best scientific blogs in Russia), where he shares new observations of the comet and other interesting facts about it.

In addition, there is a very interesting section dedicated to the comet C/2010 X1 on astro-forum.

You can find information about the Comet Elenin all through the Internet (for example: site JPL Solar System Dynamics (NASA), in database of Solar System minor planets’ section). Plus, there is an applet for visualization of comet’s diagrammatic movement (setting [show orbit diagram]).

According to MPC data, the Comet has 1.8396 degrees inclination (dihedral angle between plane of comet’s motion and ecliptic), 0.48244 AU perihelion, that matches Mercury orbit and 1.00003559 eccentricity, that ranges the Comet in hyperbolic class. September 10, 2011 the Comet Elenin will pass the perihelion.

The comet’s motion parameters are unique.


Implementation of the CoLiTec software (2010 results)

In 2010 CoLiTec software started to be used in two observatories regularly observing asteroids (Andrushevsk Astronomical Observatory (AAO) – since May, Russian remotely ISON-NM observatory – since the end of November). Using the present software, AAO observers discovered and obtained temporary MPC names for 25 asteroids (May 2010 – January 13, 2011). Implementation of CoLiTec software in ISON-NM observatory significantly increased number of observing asteroids and their observations. Using the present software for a month and a half (up to January 13, 2011), ISON-NM observers discovered 133 asteroids. The absolute record of this observatory using СoLiTec software, represents 3868 observations of 967 asteroids and discovery of 32 asteroids (night January 3, 2011). СoLiTec application also led to the discovery of the comet C/2010 X1 (Elenin) December 10, 2010 – the first comet discovered by a Russian astronomer for the last 20 years.
