Projects overview

projects1Here you can see a list with my current and future astronomy projects. Some of them are in progress, some of them are still not started, and some are frozen because of lack of time. If you find some of them are instresting and you will like to join please feel free to ask for details on lucian DOT curelaru AT gmail DOT com. Of course I will do my best to share all my knoledge in order to help you understand and work in any of this projects. All this projects are volunteer projects where I work just for fun with no money but also no deadline stress :). Some of these projects are not exclusively mine but has been started by other authors ( Ovidiu Vaduvescu, Marcel Popescu, Bogdan Danila ). I just took over and continued/improved them. Also some projects use parts and know-how from EURONEAR projects. Of course any contribution will be appreciated and mentioned.

  • EURONEAR VIMP ( Virtual Impactor Mega Precovery )
    • OVERVIEW: This is an archive datamining project which tries to identify in archive images containing but not reported VI asteroids positions using the EURONEAR Mega Archieve and a special developed tool. This tool produce a list of achieve images that could contain particular VI objects. Each proposed candidate have to be analysed, identified, measured and reported using diffrent other tools.
    • GOAL: It is important to contribute with new data to the VI asteroids because they are objects with some impact risk for our planet (even if is mostly a small impact chance it is not zero ). They have uncertainities in their orbits which have to be reduced in order to clarify if they are dangerous or not. By adding new observational data the orbit is improved and this allow to clarify the situation of each VI. Most of them will be probably eliminated from the risk list. The results are directly reported to MPC
    • STATUS: The VIMP tool is now able to produce a list with canditates with some scoring info allowing to choose the most important ones for analyse. Now I’m in the phase of analysing some candidates. Probably there will be needed also some improvements on the VIMP tool in the future, but now most activity is focused in produce and analyse VI new data for the moment.
  • Neglected double stars measurements with my instrument
    • OVERVIEW: There are a lot of double stars that was not measured for a long time due to the huge amount of such objects and the limited alocated resources for such activity. Getting new measurements for these neglected objects can help in monitoring these objects and future computation of orbits for some of them. In this project I take images of 5-arc or wider separated double stars visible from my location, I analyse them and extract astrometry for all double stars in the images
    • GOAL: Measure as many neglected doubles as possible for Stardust Observatory location and equipment limitations. Resulted data are periodicaly published in a report-article in JDSO magasine.
    • STATUS: This project is continously runing for a long time.  Whenever weather and time permits some images are taken and afterwards analysed. Periodicaly the results are reported.
  • Neglected double stars measurements by datamining on OmegaCAM archieve
    • OVERVIEW: There are a lot of double stars that was not measured for a long time due to the huge amount of such objects and the limited alocated resources for such activity. Getting new measurements for these neglected objects can help in monitoring these objects and future computation of orbits for some of them. In this project I look for images containing neglected doubles using EURONEAR MegaArchive and some special tools developed by myself for double stars datamining. Founded objects are measured and reported to USNO (which manages WDS Catalogue) via JDSO magasine.
    • GOAL: Measuring as many neglected doubles as possible , concentrating on objects that are not accesible for small amateur instruments but accesible for instruments like VLT-VST. Resulted data are periodicaly published in a report-article in JDSO magasine.
    • STATUS: A first phase of this project was finished. There were developed the needed tools and a small set of 20+ neglected was measured to demonstrate this ideea and proposed methods are reliable. All this was compiled in an article for JDSO which is scheduled for publishing in 1 oct 2018. In the nearest future a set of new measurement process shall be started using the established tools and procedures.
  • Double stars automatic data reducer
    • OVERVIEW: A lot of double star astrometry can be produced both from new produced images by our telescopes or even from big telescopes image archieves by datamining. But the reduction process is in present a quasi-manual one which even is not very labourios it consume human reducers time. For sure , at least for not problematic objects, this process could be completely automatised, leaving for human reducers analyse only the odd objects. A set of tools to automate this project should be developed and used on diffrent observatory or archive images.
    • GOAL: Develop tools to automate the double stars reduction process.
    • STATUS: The project is not started. Some ideeas and solution are available.
  • Meteors monitoring and measuring with my meteor station
    • OVERVIEW: Many amateur astronomers in the world use “meteor stations” to automaticaly observe meteors. These stations are in fact sensitive cameras pointed to the sky in the night and conected to a computer. The computer runs a software which is able to identify the meteors in the camera live image and save only small movies containing such objects. These movies can be later analised in order to extract some data for the captured meteors. Also it is used that multiple such stations are organised in networks in wide geographic areas and the data is analysed in a comparative manner in order to obtain more usefull data using some triangulation tehniques.
    • GOAL: Find out how this data can be used. Integrate my observatory station in a network and report usefull data ( directly to IMO or indirectly via a meteor network )
    • STATUS: In this moment the station is functional and is able to produce data each night but I do not have time to analyse the data, report and integrate with some network.
  • EURONEAR Datamining tools improvements
    • Some already developed EURONEAR datamining tools need some features and/or improvements in order to be more efective and usefull.
      • Image automatic downloader: A script of piece of software which is able to automatically download lists of archive images from mega-archieve listed collections (ESO,CADC,SMOKA,ING,NVO,LCO). Unfortunately in most cases the archieves websites are quite complex so probably some custom solution is needed for each.
      • New instruments to FindCCD: FindCCD is a tool which help identifiying the position of asteroids, double stars or fixed objects on mosaic cameras. This tool indicate which image have to be used when search such an object (on which image from the entire mosaic the object should be). In this moment only a part of the mosaic cameras available in Mega Archieve are also implemented in FindCCD. We have to add also other cameras. This mostly implies studiying each camera website to find the mosaic dimension and arrangements and do some computation in order to produce a matrix which can be introduced in already existing FindCCD tool.
    • STATUS: Not started yet.
  • EURONEAR Mega Archieve webcrowlers
    • OVERVIEW: The EURONEAR MegaArchieve tries to index  big images archieves available on the internet in order to allow easy manual or automatic search usefull for archive datamining projects. In the present days the archive contains 110+ instruments and 15+ million images from 6 diffrent archives (ESO,CADC,SMOKA,ING,NVO,LCO).  The MegaArchive use custom developed webcrowlers for each archieve which update daily the archieve with new added images in last observing nights. We intend to constantly add more such crowlers to extend the MegaArchieve range. Developing such crowlers needs some software development experience.
    • STATUS: Paused for a while due to other projects, but it will be resumed in a near future.
  • Asteroid light curves with my instrument
    • OVERVIEW: A new and pretty untouched area these days is the asteroid light curves observation. This kind of observations are usefull for determining some physical data of the asteroids. Due to the fact that there are just a small fraction of the known asteroid already observed this way and also that it cosumes lot of observing time, these types of observations are apropriate for small amateur setups like mine.
    • STATUS: I’m currently in the phase of preparing tools and understanding the observing and data reduction processes. I hope in the near future I will be able to perform some testing observation on a simple object, and afterwards , if everithing is ok , starting real observations that can be reported and usefull.
