    Aciqra

    A virtual planetarium for observers of the real sky.

    Aciqra is a virtual planetarium and sky mapping program which tracks celestial bodies including planets, deep sky objects and stars to an accuracy of a fraction of a degree for thousands of years into both the future and the past. It includes the 2.5 million stars of the Tycho-2 catalog supplemented by data of 120,000 stars from the Hipparcos catalog, 13,000 deep space objects from the NGC and IC catalogs and a large number of asteroids and comets from the Minor Planet Center. The program is platform-independent and can be made to work on most modern computers that support OpenGL.

    Slnečné škvrny

    Slnečné škvrny

    Program na spracovanie pozorovaní slnečných škvŕn

    Program vznikol ako ročníková práca z informatiky na Gymnáziu Jána Adama Raymana v Prešove. Vznikol na základe programu PC – Sun (autor: V. Feik), ktorý slúži na digitalizáciu pozorovaní Slnka na Hvezdárni Františka Pešty v Sezimovom Ústí (ČR). Program Slnečné škvrny slúži na digitalizáciu pozorovaní slnečných škvŕn a fakulových polí. Pozorovania sú následne štatisticky spracované do tabuliek a grafov popisujúcich aktivitu Slnka. Program taktiež umožňuje výpočet fyzikálnych súradníc Slnka, Carringtonovej otočky a juliánskeho dátumu. Program je určený pre astronómov – amatérov aj profesionálnych astronómov. Program rieši komplexne problém pozorovania slnečných škvŕn. Taktiež realizuje kontrolu vstupných dát od užívateľa. Pre správne fungovanie programu je potrebné dať užívateľovi právo zapisovať do priečinku "C:\Program Files\Slnecne skvrny".
