It looks to me like Aqruarius rises about 3am local time and the sun  
follows roughly 6am so where-ever on the Earth is favored for the  
right time is going to be a fairly narrow window of just a few  
timezones. The  range, (at the bottom of the page) 13:30 - 15:00 UT  
and the UT times correlated to timezones....

http://sunearth.gsfc.nasa.gov/eclipse/SEhelp/TimeZone.html
  		Atlantic Standard Time (AST) =  UT - 4 hours
                 Eastern Standard Time (EST)  =  UT - 5 hours
                 Central Standard Time (CST)  =  UT - 6 hours
                 Mountain Standard Time (MST) =  UT - 7 hours
                 Pacific Standard Time (PST)  =  UT - 8 hours
If Daylight Saving Time is in effect in the time zone, you must ADD  
one hour to the above standard times.

So the start of the period of 13:30 hrs UT would be 9:30am for the  
eastern US .... Pacific would be 6:30 am.... look like it's out over  
the Pacific somewhere....

Hawaii's at -10 hrs, http://www.timetemperature.com/tzus/ 
hawaii_time_zone.shtml (note also no Daylight Savings time)

So their start would be 3:30am to 5:00am. Perfect for the streams.

Did I get that right? areas of the central Pacific from 30 deg N and  
on south?
