I found this NASA website which says that to predict eclipse, we should solve the Besselian elements ..what does this mean, how can I solve for Besselian elements? Is there a numerical method? I need to find the circumstance (length of eclipse etc) at a given coordinate..Sorry I am very new to astronomy so my question might be basic..
