Bill and Carol Beverly and I started the day with a sunrise eruption of Morning at 0532 with pink on the western horizon.  I came home to take a nap this afternoon, then went back to the Lower Basin for Great Fountain.  I wanted to see just how short the Great Fountain interval would be since it had a very weak eruption this afternoon--a five minute third burst and no fourth burst.  I had gotten the start of overflow and Great Fountain.  One minute before the window opened, Bill Beverly called the start of Morning.  Dave Leeking and I scurried over for the second half of the eruption.  It was warmer than it was this morning, so we could see the water much better (although comet tails also have a certain appeal).  This evening's eruption was also accompanied by pink on the western horizon--from sunset this evening rather than from sunrise.  Duration of this morning's eruption was 17 minutes; duration of this evening's eruption was 24 minutes.
 
This evening's eruption was preceded by an eruption of Fountain at 1158, which had a duration of only 37 minutes, less than the 40 minutes that had been the previous cut-off.  So, although the post Fountain window of 8-10 hours hasn't changed, it is no longer safe to skip windows after a Fountain with a duration less than 40 minutes.
 
Dave reported Great Fountain at 2159ie, for an interval less than 9h5m.
