Thanks so much for this heads up last night. I enjoyed a marvellously clear
view of the ISS. It gave me a thrill following its journey across our sky
knowing Chris Hadfield is at the helm. Such an exciting and humbling
experience watching the ISS in its orbits.
Cheers,
Judy

Subject: [NatureNS] Space Station Pass Sunday evening
Looks like it will be a clear night tonight, so if you get this notice in
time you may wish to catch the
SPACE STATION PASS
There are only a few passes of the ISS left in this round of evening passes.
There is very good visible pass this evening.
TIMES and DIRECTION (particularly for Halifax area, times about the same for
other parts of N.S., track may be slightly different)
-starting out of the NW about 9:15 p.m.
-reaches its peak elevation of about 65 degrees above the NORTH NE Horizon
at 9:17:45 p.m.
-about 9:18 pm it goes through the Big dipper, especially the handle (close
to overhead)
- ends in the ESE about 9:20 p.m.
TO JUDGE ELEVATION
horizon at eye level is 0 degrees
directly overhead (the zenith) is 90 degrees (Big Dipper is near overhead at
pass time)
halfway from horizon to overhead is 45 degrees
a closed fist held vertically, extended to arms length, and sighted against
the sky, marks off an angle of approximately 10 degrees.
APPEARANCE of Space Station (ISS)
Looks like a bright star coming from the westward direction (a bit orange at
first but getting brighter and whiter as it gets higher and closer to
north). It glides slowly across the sky, taking about 5 minutes on tonight's
pass.
It will get as bright as or brighter than Jupiter (which is quite bright,
about half 3-fists up in the westward)
STAR CHART showing the pass track, times and surrounding brighter stars
in the sky can be accessed at this link.

lifax&alt=45&tz=AST&satid=25544&mjd=56404.0123308333&type=V> STAR CHART of
ISS Pass
Because of lingering twilight and the brightness of Moon (just under LEO the
Lion) only the brighter stars (like Regulus in LEO) will be seen easily.
The Dog Star < Sirius, is quite bright low in the South. Because of its
brilliance, Jupiter is easily seen in the lower half of the SW sky with
Aldebaran a bit below Jupiter.
Orion's stars are generally bright enough to be seen but Orion is getting
quite low in the WSW this time of year and will soon be falling into the
advancing Sun as the evenings grow longer into the twilight.
For pass data reference go to this link and click on ISS under SATELLITES
(you can also at this link, select a more specific location -this one is set
for Halifax):

Perhaps Chris Hadfield is looking down taking photos of the nightlights over
Atlantic Canada : )
