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 ?
