I think we all greatly appreciate Sherman's information about ISS
passes, but am I alone in wishing it might be possible for you to let us
know earlier in the day of, or the day _*before*_ the pass Sherman? I
love watching it, but frequently don't find your evening email till the
next day and I have missed so many opportunities, including last night
as a result, which is so disappointing and frustrating.

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.
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):
