I have just nicely arrived inside after a bit of star gazing with  
some friends.  A beautiful clear sky, lots of stars, Mars and Saturn.

OBSERVED PASS OF ISS AND SPACE SHUTTLE, BUT NOT JULES VERNE
However, regarding the Three Space Craft:  we did not manage to spot  
the ATV (Jules Verne) re-supply vehicle, it apparently was too dim  
for us to see before it entered Earth's shadow or else eyesight was  
just not sharp enough.   We had an excellent horizon to work with.

Right on time, we had no difficulty spotting the ISS. It was very  
low, but quite bright.  Moments later we picked up the space shuttle,  
a bit dimmer, coming along behind.  They were in sight only briefly;  
each disappeared in turn, into Earth's shadow located under the hind  
leg  and tail of Orion's Big Dog (Canis Major with the very bright  
star, Sirius).

WE ALSO SAW SATURN AND REGULUS
Our little group spent the next half hour wondering through the  
constellations.  Of particular note was LEO.   LEO rising high in the  
southeast, in mid-evening, is A SURE SIGN OF SPRING!  even though  
tonight's frigid air was biting our fingers.   This spring LEO is a  
little more special, his brightest star, REGULUS, has a PARTNER.     
Saturn is with Regulus, forming a nice BRIGHT PAIR above the  
southeast during mid-evening (Saturn is the brighter and the most  
east of the two), you can't miss it.   By MIDNIGHT they are high in  
the SOUTH.

This is a great opportunity to see the result of planetary motion.   
Over the next month, observe as Saturn gets closer to Regulus .   
Saturn is really moving eastward (between 10 and 12 km per sec) but  
because we, on our little planet Earth, are whipping by Saturn at a  
pretty good clip (about 30 km per sec along our orbit inside  
Saturn's), an angular shift of Saturn is created against the star  
background.  This causes Saturn to look as if it is moving westward,  
drawing closer to Regulus.  WATCH FOR YOURSELF, over the next month,  
as this motion continues.  Late April - early May Saturn will appear  
to resume its eastward motion.
