Beyond the 5 MCSE & 5 MCLE Canons ü Retirement from NASA in 2009 ü Work on Eclipse Canons is Completed ü Inconvenience of Maps and Catalogs in separate publications ü Frequent use of eclipse predictions within ~500 years of present ü What about combining a subset of the Canon and Catalog into a smaller book (less pages)? ü Why not make larger maps? ü Personal or Public? ü If Public, how to publish? (print-on-demand)

Rational Behind New Eclipse Canons ü smaller (fewer pages) Canon containing both maps and catalog ü shorter time interval to cover period most frequently used (± 500 years) ü larger maps with more detail ü use newer ephemeris (DE 406) as consistency check with 5 MCSE (VSOP 87 & ELP-2000/82) ü NASA Canons are "out-of-print" since only funded one printing ü option to publish the canons in a standard (black & white) and color editions ü good project to test print-on-demand process for future publications (eclipse bulletins? )
