On the night of May 3/4 an Ariane rocket should launch
the Spot 5 satellite into sun-synchronous orbit from Kourou.
Launch will be nominally at 01:31:46 UT May 4 (= 9:31:46 pm EDT May 3).
If delayed the launch will be 12min or 18 min later;
or the same 3 times on later days.
Launch will be northwards into a near-circular sun-synchronous orbit,
and last part of the launch will be visible from the eastern US and
Canada. The rocket will be to the east of M America, travelling
northwards.
The elevations below are for a nominal launch time, but will be
similar for the later launch times.
Column T-H0 = time from launch in minutes
LongE,Lat are longitude & latitude of the rocket
Ht = height in km

At 18.5min after launch the rocket stops firing and so will
disappear from view, but shortly after the rocket + attached
payloads come into sunlight, and so will be visible again.
I will be at the launch site, and will lose sight of the
rocket maybe 13min after liftoff.
