The SPACE STATION (ISS) is now making visible passes in the evening  
sky.  There is a very nice pass this evening and with the possibility  
of a nice clear evening, you might want to catch this one because  
VENUS is also putting on a nice show tonight as well.

ISS comes out of the WSW after 9:18 pm , reaches its peak about 9:21  
pm, high (nearly overhead) to the NNW, and disappears into the NE  
just before 9:23 pm. Its brightness (reached just after it attains  
its highest point) should almost rival Venus.  Venus by-the-way is  
that very bright "Evening Star"  well up in the West, lingerings well  
above the horizon into the NW for quite a while after sunset.

Tonight VENUS is in a special position.  It is paired with the  
Pleiades (Subaru), or  "the Seven Sisters" . From 8:45 pm until at  
least 9:30 pm the sky will be dark enough to enjoy the cluster and  
Venus situated about 3 degrees apart, placing them within a binocular  
view of each other. The view, especially in binoculars, should be  
well worth the effort. Light from Venus tonight is taking  about 8  
minutes to reach us, tonight's light from Pleiades has taken about  
400 years to get here.

Perhaps AN IDEAL TIME to do this would be shortly before the Space  
Station arrives, say about 9:10 to 9:18, the ISS comes into view just  
after that in approximately the same part of the sky(a little more  
around to the north ( look for a moving star, dim at first but  
quickly brightening).  As a point of interest, just as the ISS comes  
above our horizon, it is near overhead in Toronto. During  a pass  
above our horizon (about 5 min) ISS travels about 2100  km (7km/s) at  
an altitude of around 380 km above Earth; I believe there are 3  
people on board the space station. If they are looking westward as  
they pass over Nova Scotia, their horizon stretches jus nicely beyond  
Lake Ontario and Toronto and just beyond that, they can see that  
beautiful,, thin, blue fringe of atmosphere that sustains us.

Be sure to dress warmly and find your darkest location looking west  
and north so you can enjoy  your view of the sky and the time you  
have to stand around outside.

Enjoy,
   Sherman
