It's passing overhead in about an hour, rising in the West at 4:03.

About 4 minutes later it will catch the sun, and appear at it's brightest at about 4:09 in the southern sky at an angle of about 60 deg from the horizon.

It will then appear to slow down and dim before disappearing into the rising sun at 4:13.

If anyone sees it, post what you saw maybe. I'd stay up but my eyelids are drooping.

It was there, right on target, appeared just above and to the right of the moon, gathered in brightness (even bright enough to shine through a thin cloud bank) and then swept of, getting dimmer to the SE horizon.

If you saw a big white blob moving noiselessy through the sky, it was the ISS.

Good display, not ideal, but good.

I wish i had seen this thread earlier. When is it coming over next?

Yeah I think I saw it then. I've never really looked up at the sky so I didn't have a clue what was what.

Still, I can say I saw it now... :)

Yes. How often does it fly over?

Well, it orbits the earth 15 times a day, but because the earth is spinning, it gradually slices over the planet, and because you can only see it when it is reflecting the sun at night, visible passes are much rarer than invisible ones, which happen all the time.

Tomorrow morning at about 4:30am is the next visible pass.

Should be a good one too, if the weather is clear, as it passes almost directly overhead.

And here's something for your diary, a Magnitude -6.7 daytime iridium flare (the sun is magnitude -27, the full moon is magnitude -12, the ISS is about -2 on a logarithmic scale)
Time:29 Aug - 18:04:51
Magnitude: -6.7
Degrees above the horizon: 72° (nearly vertical)
Compass Direction: 306° (NW )
Satellite: Iridium 65

That was amazing Phan! :D
I was expecting it to come from the East for some reason. I stood there looking but once i saw it (from the West) i knew what it was.

Brilliant stuff :clap:

Mind Boggling when you think about it!

I was fast asleep last night, due to having been out the night before.

for Vidster and anyone else's benefit, I'll try and remember to post ISS passes here when I can, as well as Iridium flares and any other spectacular sky event. August has been pretty good so far!

Poo. Sorry about that. It shoulda been there (if I copied the info accross (ahem - I will check)).

Well there a few more more tonight

21:13:58s - Direction SE (142 deg) Elevation 19.7 degrees Magnitude -1.5 (dim)

21:19:18s Direction SE (142 deg) Elevation 20.1 degrees Magnitude -1.8(dim)

23:25:53s Direction W (263) Elevation 16.4 degrees Magnitude -3.1 (properly bright that one, but low)

03:17:09 Direction ESE (117) Elevation 23.6 degrees Magnitude -3.7 (again very bright)

05:23:12 Direction SW (214) Elevation 65.9 degrees Magnitude -5.6

Viewing conditions should be pretty good.

the next visible ISS pass is
9/01 09:06:57pm
Rises: SW
Sets:E
Duration:09:36
Lit by sun (visible) for:05:05
Max Elevation SSE 21 deg above the horizon

Phanerothyme
29-08-2005, 20:02
They won't be spectacular, even in a clear sky, but you're looking for a light slowly winking on and off, brighter than all other stars, but not 'spectacular'.

20 in about 20 minutes look to the South East sky, low on the horizon at about 20 degrees.

How high is 20 degrees?

make a simple inclinometer http://www.exploratorium.edu/math_explorer/howHigh_makeInclino.html

Basically if you live surrounded by terraced housing you wont see it from your garden. A good spot with a clear view of the horizon is required.

Now, you have 12 minutes to build your inclinometer!

vidster
29-08-2005, 21:24
I've already missed the first two trying to sort computers out :rolleyes:

I'm going to see the third one for sure! (unless the hills to the west block it)

06-09-2005, 20:52
Hey Phan,
I don't suppose you know if the ISS or something similar passed over tonight (Tue 6th) at approx 21:46 from the West (possibly NW) direction?

I've just got back with the dog and saw something awfully bright that looked just like the ISS i saw a couple of weeks back :?

The Space station will be overhead in about 10 minutes.

Look into the western sky at about 5:38 it will track from the western horizon, up into the southern sky and will set in the SSE.

Looks like a plane at first...

Eyes up for a full house!

Yeah - about 6pm is good for me, but make sure they know I'll be on a meal break. If they're late I'll never look for it again!

Oh, and not to steep an angle of approach, I'm not looking up that much.

Thanks very much.

The best they can do, if they floor it, is to get to sheffield at 17:38:38 tonight (Jan 13) - same deal, rising in the west setting in the SE, climbing to about 30 deg above the horizon.

The whole pass takes 9 minutes, but the ISS will only be lit by the sun for about 7 minutes.

And then again on Saturday 16:28:11. This one goes right overhead, West to East.

Two more passes tomorrow evening - in about the same bit of the sky, close to the moon.

Saw it again tonight, Phan. Travelling over the eastwards side.....seemed to be some illumination on each side of it....definetely not a plane though.....looked slower tonight because it was well past it's zenith when I went outside. at about 6.33 pm.

Will be there for the next pass tonight ...... though it's like a fridge outside again.:banana: :banana: :banana:

the NASA J-Pass app is back online - http://science.nasa.gov/Programs/Pagebuilding/trackJPass.asp?zip=&latitude=53&longitude=-1&B1=Go

tomorrows 18:50 pass is lit for the whole 10 minute overflight, almost directly overhead (azimuth 63 deg)

and here's a pic I took last night - not impressive, used the 4 second "fireworks" mode on the digicam to capture it - http://www.netheredge.com/galleries/iss-1.jpg

(hint - it is the straight line on the left - the big blob in the middle is the moon)

Missed tonight's visible passes though ... glad the Vidsterette thought it was cool - Britain needs astronauts and space scientists if we want to be a part of the Space economy and we will be relying on people like her (and my boy!)

It looks like a big blobby white star that takes about 10 minutes to go from one horizon to another. It is always passing overhead, but can only be. seen at night when it is able to reflect the suns rays into your eyes. Visible passes are much rarer than invisible ones.. It should be brighter than anything else in the night sky apart from the moon. If it has any flashing lights on, it is an aircraft.

There are two good passes tonight to be seen if the sky is clear enough:
1. 20:52:34 - rises WSW; sets E; lit by sun (visible) for 08m54s; Max elevation 44deg in SSE

2. 22:27:27 - rises W; sets ESE; lit by sun (visible) for 05m22s; Max elevation 56deg in S

Phan, it's not that I don't appreciate the info, more that I don't have a compass...

Any chance you could do a screen grab from Google Earth, and show the rough trajectory of the station over Sheffield?

No worries if not!

Phanerothyme
28-04-2006, 11:57
You know where north is, right? You won't need exact angles or owt. It is passing over the UK slightly south of sheffield, at an altitude of about 400 km.

No compass required, just look to the southern sky at the allotted time (it is very punctual)- and look for a bright object travelling from right to left at a fair clip.

Cheers, my garden faces due south, but I may go to a less cluttered area.

The two pases you've mentioned appear to be at identical times, are they the same pass, or is it a typo?

I think you will be out of luck anyhow, the cloud is looking pretty set in.

But I've corrected the times, I had posted the same pass twice.

I think once you've seen the ISS for the first time it becomes instantly recognisable in future sightings.

When Phan posts a time it appears exactly on time. My daughter loves going out to see a 'space ship' passing over ;)

Psyn - do what I do, subscribe to the NASA J-Pass generator here - http://science.nasa.gov/Realtime/JPass/PassGenerator/

It emails me details of all passes overhead. For reference Sheffield is at about 53 deg latitude and about -1 longitude.

You can also have a lokk round the nasa j-pass site for links to othr realtime displays and such cool stuff.

Using Jtrack 3D I can see the ISS is just passing over Capetown, SA.
