We will not be doing Astronomical Observing from Fishcreek Observing Site on Friday 12/25/2009 at 6:08:26pm (nautical twilight)
but this information is being provided in case you have an opportunity to observe from a reasonably close location - allowing
for time changes, of course.  All rise/transit/set times will be fairly close if you're within a 50 mile radius of Stow, OH USA.
                    Sunset: 5:05pm
       Civil twilight ends: 5:34pm
    Nautical twilight ends: 6:08pm
Astronomical twilight ends: 6:42pm
