Uvazhaemye, izvinite, chto ya vtorgayus' v oblast', v kotoroi nichego ne smyslyu, no  
mne nuzhna informaciya vot kakogo roda. Est' li v Internete informaciya o  
solnechnyh zatmeniyah v proshlom? 
 Esli ya horosho ponimayu, to mozhno ne tol'ko rasschitat' solnechnye zatmeniya v  
budushem, no mozhno eto sdelat' i v proshloe. A mozhet kto-to uzhe delal podobnye  
raschety?  Mozhet, est' programma, na kotoroi mozhno takie raschety proizvesti?  
Budu Vam priznatelen za informaciyu.

Podobnye rasschety deistvitel'no est'. V kachestve instrumenta dlya raschetov mozhno  
vospol'zovat'sya kakim-libo virtual'nym planetariem, naprimer, Redshift. 
On-line informaciyu po zatmeniyam za period s 2000 g do N.E. po 3000 g N.E. mozhno  
naiti na saite "Astronomiya dlya shkol'nikov"  
(http://astro.physfac.bspu.secna.ru/HC/eclipses/SEatYear.php) ili NASA
