Iridial Tabulation
Sat, 16 Oct 99 19:22:00 NZST

Hello from New Zealand,

Its cloudy outside at the moment in our (Southern Hemisphere) spring.

So to do some "visual observing" I have had to use my PC.

I was fascinated with Walter Nissen's Iridial tabulation. And so
wanted to verify for myself the concept, but what is the easiest
way to do so -

I recently downloaded "SatScape" a cute UK freeware satellite
viewer (most notable by the fact it talks to you). Its like
having Stephen Hawking sitting next to you reading out what
satellite is popping over the local horizon. The other attribute
is has (over most others) is that it can real time plot hundreds
of satellites at once.

Checking out the Iridium "procession" seemed like an excellent
task for it. At the flick of the mouse (and the latest Celestrak
Iridium TLE's) I plotted all 90 Iridiums on a lovely map of the
world. Setting a timer for 15 minute intervals, I started to
read a book, and when the timer went off I would note the order
of the Iridium positions against Walter's table.

Talk about armchair satellite viewing !!!

Anyway, I offer the following comments to add to "perfecting"
the wonderful table of Walter's.
