2012 Calculations of Dual-Transits are Finally Here!

Thanks to the Transits Page, the 2012 results are finally here! "During 2012 Earth experiences 18 dual satellite and 17 dual shadow transits of Galilean satellites of Jupiter," opens the document. (For comparison, 2011 has 18 dual-satellite but 20 dual shadow.)

Longest Dual Transit = 2012 Jul 28 = 02h 02m (Io and Europa)
Shortest Dual Transit = 2012 Jul 10 = 00h 00m (Io and Europa)

Longest Dual Shadow Transit = 2012 Jul 28 = 02h 01m (Io and Ganymede)
Shortest Dual Shadow Transit = 2012 Aug 18 = 00h 08m (Io and Europa)
