The one I sent this morning did not post yet (5:30 p.m.) ????  I'll  
try posting again.
*********************
That was a very exciting pass last evening. Many (except parts of  
PEI, parts of Cumberland Co and North Colchester) were able to  
observe and others even photographed the track of the two craft as  
they passed (see http://www.spaceweather.com/ for some track  
photos).   Discovery was in the lead (much dimmer); the ISS was a few  
seconds behind. The combined human population making the pass above  
us was 13.

Discovery is SCHEDULED TO LAND Thursday at 8:05 p.m. ADT ( http:// 
www.nasa.gov/mission_pages/shuttle/main/index.html ), in the  
meantime, as far as I can see presently,  the Shuttle is orbiting  
several seconds (perhaps about 45 sec) ahead of the ISS and therefore  
both should make another interesting pass this evening between 9:08  
p.m. and 9:13 p.m.   Note that the shuttle times could be different  
by the time of the visible pass tonight,    but the ISS times will be  
still on this schedule  and, hopefully, the shuttle will only be a  
short distance ahead.  This is the link I've been following for  
checking their location relative to each other. ( http:// 
www.n2yo.com/?s=35811|25544  )  It uses a Google Map so when you  
link, zoom in a bit to show the separation relative to Earth  
Geography.   ...and if you click on the ISS symbol you can choose to  
keep the selection centered while you zoom in or out. Also, at the  
site, predictions of pass times can be obtained.  The following is  
also a simple pass schedule source based on postal code
(  http://www.spaceweather.com/flybys/? 
PHPSESSID=g8qk1bhbphu63jt88v9drvd3s5 )

MAIN PASS DETAILS
For Maritime Canadians, the pass will be a nice one (if cloud does  
not get in the way).  The ISS pass begins shortly after 9:08 p.m.  
appearing out of the WSW.  It reaches the peak of the pass at   
9:11:31 p.m., high in the NNW .  It enters Earth shadow in the NE  
about  one minute later.   The Shuttle if it remains at its present  
spacing, will be about 45 seconds ahead of ISS and is the dimmer of  
the two. At the peak of the pass for Annapolis Valley observers, it  
will reach about 65 degrees above the NNW horizon (that's a nice high  
altitude, getting close to overhead (OUCH my neck!)). If you are NW  
of the Ann. Valley , say, in St John or Moncton it will pass  
essentially OVERHEAD!  If SE of me, it will appear a bit lower,   
toward the north.

See this link for the overhead track (the broken line represents when  
the track hits Earth's shadow).
( http://www.heavens-above.com/gtrack.asp? 
date=40066.0079921782&lat=45.100&lng=-64.250&alt=54&loc=Avonport&TZ=AST& 
satid=25544 )

Both shine by reflected sunlight from their 350 km height above  
Earth, zipping along at about 7.5 km per sec.; the ISS reflects much  
more light  than the Shuttle (ISS brighter than Jupiter, shuttle  
about like a bright star).  Their light shines continuously where as  
passing aircraft have flashing lights.

The ISS disappears into Earth shadow near the constellation,  
CASSIOPEA.  If you are interested in a star chart of its track drawn  
for Avonport (Annapolis Valley view) go to

SatID=25544&lat=45.100&lng=-64.250&alt=54&loc=Avonport&TZ=AST&Date=40066 
.0079921782 )

The ISS makes  another good pass Thursday evening but if all goes  
well the shuttle will have landed by then.

This link will get you pass details.

Happy observing,
