I've started looking out for Iridium flares.

I've noticed two things. They don't always flare at the apponted time.
Also their flares appear to be restricted to a certain part of the
sky. Namely in the south east at my location which is Adelaide,
South Australia.

True.

I always double-check heavens-above.com and callsky.com.
Heavens-above seems to be using more restricting conditions, such as sun
altitude (at least -10 degrees). I estimate a 20% misses.
I noticed that in winter the most frequent flares are SE and NW in summer
(Italy). This might be due to sunset/sunrise time variation.

I use Orbitron which has a good flares predictor application.

I also see flares which are in the Northern sky.

Hi Daniel

Did you try heavensat? (http://www.heavensat.ru/english/). I find it to be
the best among free satellite tracking programs. Displays stars and has
lots of other goodies. Try it.
I also use Orbitron, mainly for downloading new TLEs.
For Iridium flares I prefer to rely on heavens-above and callsky, because
TLEs do not bring informations useful for flare calculation. At least I
believe so; am I wrong? -

I've downloaded and installed heavensat, but it doesn't have a help
file. I need to be able to install the satellite elements and most
importantly, how to exit the program. :-)

I see no mention of callsky in Google, Is it a satellite tracking
program ?

You can exit Heavensat by clicking on "Common" in its
toolbar, then clicking "Quit." Or you can just click on
the X in the screen's upper-right corner.

I put the satellite elements in .txt files, and place them
in Heavensat's TLE folder. Then click on "Satellites"
in the toolbar, then click on "Satellite bases" and
checkmark the file(s) you want to use. (Alternatively,
when you're in the main screen you can hit
Ctrl-b to get the list of TLE bases.)

Good morning (or rather good afternoon?)

Calsky. ( http://www.calsky.com) is a free site for all astronomers and
satellite observers.
Register, setup your location and navigate its menus. You'll be delighted.

Heavensat has a short help file available, but ... in Russian language!
Telescope driving is not active yet.

Thanks for that information, Giuseppe.Calsky is a good sight.
I just wish the star maps in the Iridium section were a bit larger,
but that's a very minor problem.
