[AZ-Observing] By The Light of The Southerly Moon

During the past few mornings, the waning moon has been shining in the south 
windows of our house.  It seemed like it was really far south, especially as I 
was watching it set over the Estrellas this morning.  It turns out that it is 
about as far south as it gets.

I plugged a time range into the JPL Horizons Ephemeris Generator 
(http://ssd.jpl.nasa.gov/horizons.html).  It shows the moon reaching a 
declination as southerly as -29d 11' tomorrow at 4 a.m., when it will also be 
due south.  This is more than 5 1/2 degrees farther south than the sun's Winter 
Solstice declination.

What this means to weekend observers is that we will have a Last Quarter moon 
that waits until 2 a.m. to rise on Sunday morning.
