ISS visible passes - ongoing thread

[Gary]

ISS back for some night passes, just been over the UK but unfortunately was cloudy here

[H.A.Bucken]

Just had a look at NASA-SpotTheStation on another tab for times. Some of the passes are quite high up during the next week. Never saw any aurora last night.

Excellent view over Rutland Water 2015 ish last night. Due again tonight

[Dan D'Air]

ISS overhead Southern GB 17.12 to 17.18 hrs tonight. (tracking West to East) . Just about the time of the docking.
If it is a clear sky, we may see supply module just behind the ISS.

Come on Tim. (It's been a while since I shouted that!)

[Gary]

Don't look like South Lincs will be that lucky Might man the scanner, to see if any comms can be heard http://www.zarya.info/Frequencies/FrequenciesISS.php & http://www.issfanclub.com/frequencies

Had some potential hits on 121.750 during the pass that just happened, didn't hear any comms just static

A couple of nights ago, I stepped outside the back door to spot a RAF Herc heading for Brize, but accidentaly spotted ISS instead! It was quite cloudy at the time, and I thought briefly that it was a star... until it appeared in another gap and I realised that it was moving. It's been a long time since I've actually looked for it.

Not much chance of seeing if from here tonight, though, as the weather's awful... and unlikely to be much better for some time, given the forecast.

It'd be nice to spot the Soyuz. I've seen Space Shuttles chasing ISS a couple of times, prior to docking.

Very faint comms on 121.750

Not sure if this link has been posted before, or if this is the place to post it.

Instead of looking up you can look down.

A few evening passes over the next few days ladies and gents.

And more passes over the next few days.

Thanks for the info, ihave 2 radio freqences for the ISS 145.5 nfm and 143.625 nfm . is it possible to hear the transmissions on an air band scanner ? any replies would be great . thanks ROB

[beefsteak]

They can be heard down here, but I don't know the frequencies, try the search engine on the top of the 'home' page

[WAP]

Due over UK in about 10mins, 8:55 for south of UK. Should be a good 6mins worth.

[WAP]

Had Data on 145.825nfm nice and clear in london, no clouds tonight and perfect light for tonights longer pass.

[ROBERT HARDY]

I Took a few shots back in February around the 12th first two 1200mm then 1680mm Canon gear.

See:
http://spaceflight1.nasa.gov/realdata/s ... on=England
and select nearest your location.
The series of UK visible evening passes have now ended.
The next visible ones will start in the early mornings and drift into the evenings.
The ISS is only visible as the Station is illuminated by sunlight (due to its altitude) but we on the ground see a darker sky towards or just after sunrise/sunset.
The NASA website (above ) explain the mechanics of it on the left of the page.

No problem
Sometimes I'm asked why you can't see it at other times when it orbits every 90 minutes.

It's because as the station orbits the same path, 51.6 degrees inclination, the Earth rotates underneath it. Each consecutive orbit pass a little further round the Earth as it has rotated.

So many orbits pass nowhere near the UK region.
When they do, the station is not visible during daytime as the brightness of the sun is greater than that of the Station.
At night, the Station is in the shadow of the Earth, so not illuminated, not visible.

Only when you get the combination of Station position relative to the UK and still in sunlight illumination, but a darker sky from the ground can you see it.
