Did I see Shuttle and ISS flares?

On Saturday 6 Aug at 8:50pm,(1950 UTC) I saw what looked like a bright
Iridium flare, it appeared and faded then reappeared at approx the same
time as another flare. They were to the NW approx 40 deg altitude. I'm
in South Lincs. The gap between them was approx a hand width when arm
extended. Also the second flare, to the right of first, left a short
and 'thin' trail like a condensation trail which was short lived.
I've searched the internet for ISS orbits but not found anything
useful. I know ISS and STS seperated on Sat. morning.
This was a fluke sighting as I was admiring the red cirrus clearing
eastwards with very clear air following.
Does anyone have a program that puts the spacecraft in that position?
or know if the Shuttle did a burn that would have caused the trail? at
that time.
Thanks for any help

http://www.heavens-above.com/ should answer all your questions.
Excellent site for tracking (or checking) ISS and Iridium timings...

Heavens Above doesn't give any (daytime) Iridium flares for South
Lincolnshire at that time.

You can't use Heavens Above to check for daytime STS passes, because it
only lists visible passes, and it thinks it only gets dark enough to see
satellites at about 9:15pm. You can check for ISS daytime passes because
ISS is included in the "Radio Amateur Satellites". There were none at
that time.

I, necessarily, had to use an approximate location for South
Lincolnshire. It's just about possible that you might get different
results if you enter your precise location details.

Note that many other satellites can flare. Iridium flares tend to be the
main ones that get mentioned because their orientation is precisely
predictable which allows flare forecasts to be made for them.
