People have been asking about statistics on Morning/Fountain dual eruptions.  Here's a brief chart, including the Fountain/Morning's Thief/Morning trifecta of today (6/13/13):
 
                                       Fountain       Morning       Morning's Thief
                                       Duration       Duration       Duration
 
8/18/1959                    Duals of Fountain and Morning occurred periodically on August 18.  Marler indicated Fountain and Morning started simultaneously on the night of the 17th, but that is not what Barry Watson, the ranger who was there at the time of the earthquake said.
 
7/4/1991                          95 min            31 min
7/5/1991                          82                    21
8/9/1991                          122                  38.5
8/28/1991                        140                  36
8/29/1991                        98                     27.5
10/30/2012                      130E                ~38 (If assume Morning started same time as Fountain electronic time)
5/31/2013                           69                   24
6/5/2013                             93                   33
6/13/2013                          189m              68              69
 
I believe the 6/13/2013 eruption durations for Morning and Morning's Thief are the longest recorded to date.
