Space Station pass this evening

calchas

Looking at very clear sky over Dublin CC.
There is an ISS pass west to east (17:07 to 17:15, highest altitude 36deg in the south. It should appear to fly high over the Wicklow hills.

Good luck and clear skies

Will be in work unfortunately, and I've got the flu... Meh

Fog ,fog, fog and yes some more fog!:mad:

jimbis

Good call!

I veiwed this thread at exactly 15:07 so i grabbed the binoculars and ran outside!
Very clear sky in dublin. That was one of the best sightings ive ever seen!

calchas

Just managed to pick it up at 17:15. disappearing to the east of the IFSC.
With clear skies there will be more chances to spot it in the next week or so.

when I get home I'll post the times for the rest of the week, easy to get from the NASA site if any want's to jump ahead

That link should work, another pass and 18.09 and the brighter pass at 19.44.

Spotted less than 5 minutes ago coming from a SW direction. Just happened to look outside at the sky didn't know wtf it was. It was moving quicker than the usuall sat that passes by the night sky and was visable for about 45 seconds and faded in about 5 seconds. Hair on neck tbh .

calchas

I tend to use www.calsky.com for ISS passes (and Iridium flares etc) as it is more accurate and detailed than Heavens Above.
However for ease of use you can't beat the simple tables from NASA.

Here are the times for the next week or so.

Here's hoping for clear skies tonight, bit cloudy now. I shall be keeping an eye on sat24.

Beginner questions:

Where do i look? (south city dublin)
What am i looking for?
And can i see it with the naked eye?

Really want to finally see this thing!

It's a bright light moving across the sky. It'll come from a southwesterly direction,usually takes about 3-4 minutes to transit across the sky. It's easily seen with the naked eye,looks like a bright star that's moving.

Hal1

I've been tracking it on this site. http://www.n2yo.com/

Diamonddec

Have just been watching it in clear skies up here in Northern Ireland ... excellent!

Hal1

It clouded over at 5:45:rolleyes:, but there was a clear spot where it passed overhead. I got the last 40 seconds or so of it. It's over Iran now.

scrubber72

full view in galway but it moved to fast to try and get my new telescope to pick it up. Jaysus it was lifting. cool all the same

I looked but didnt see it! was just looking toward the wicklow mountains and all i could see was clouds!

calchas

Just saw the 17:55 pass. Lots of cloud cover in the west. Picked it up about due south, but until it was past Alderbarren it was mostly above cloud. As it passed Betelguise it was still very bright in the sunlight passing just to the south of the red giant. Just after that it quickly faded and disapeared into the earths shadow.

Good to see as the next pass tonight will be hard to see as it rises and passes almost straight away into shadow.

Clear skies

PS King-stew, if you missed it it looks a bit like this: http://www.flickr.com/photos/32407212@N03/3944927353
The www.calsky.com site will show you where through (with reference to the stars) the sky it travels

It was relatively high in the sky and it passed by Alderbaren

Thanks calchas, very helpful.

On a side note, what the hell was the second light in the video??! :eek:

calchas

has anyone here tracked this with a telescope befere. I'm thinking of trying for it but I think it's a fairly tough project

I'd like to say it's a special case of 'strange orange light seen over Dublin bay'.

But

The video is a time lapse (to try and get the right brightnes and feel) therefore it's faster that the actual pass, the second light is a plane outbound from dublin turning south close to our house. We live under the western flight path.

NoQuarter

Aaah, should have figured it out from the cloud movement, thanks!

Hal1

I'm looking at that link I posted earlier and the ISS is about to pass again. I didn't see anything on nasa's site about this. It's probably too far south though to be worth a mention. It's over france already.

NoQuarter

I saw it clearly on that pass, came straight in from the west, but why, when it seems plainly visible in the sky does it suddenly fade?

The earth's shadow makes it look like it disapear's. Are you far south? I'm in the big smoke meself but didn't see it on the second pass. Too much cloud and light pollution :rolleyes:.

NoQuarter

Im in dublin 12, it wasnt there for very long, i looked out as the satellite was approaching ireland about 30 seconds later it was fading!

From the way Nasa reports the passes I think it only mentions those that are visible when at highest altitude (close to due south) If That is true then so is your theory.

I still prefer the www.calsky.com site, but it's not so easy for casual observers.

scudzilla

Awesome, i saw this thread and went up to Howth Head with my wife to see it, was really really cool, i was expecting it to go right across the sky but it disappeared after about 30 seconds, why's that??

calchas

For us to see the ISS (or any other satellite) we need 3 things:
The satellite needs to be in our line of sight, above the horizon.
The satellite needs to be in sunlight.
The sky needs to be dark enough for us to see the satellite against it.
As the ISS is in a relatively low orbit only those passes around dusk and dawn allow this.
The last pass this evening passed from sunlight to shadow just after it rose above the horizon. That's why it seemed to fade and disappear.
Clear skies

I don't get this:
on the NASA site it gives the time of the 2 passes visible from Cork on Sunday as:
4:42 PM and 6:17 PM local time

on the n2yo site, it gives the time of the 2 passes as:
18:10 - 18:20 (UTC) and 19:45 - 19:55 (UTC).
The heavens-above site gives the times as:
19:13 - 19:17 (UTC+1) and 20:48 - 20:48 (UTC+1)

the n2yo and heavens-above sites seem to match, but the NASA site seems to be a couple of hours off.

When should I be looking for the ISS?

Looking for Waterford NASA give 18:13 and Heavens above give 18:14 and 19:48.
The reason NASA dont give the second pass is because it will only last a few seconds. In the example you give above the Heavens above times have a UTC+1 after them. We ate currently on UTC so knock off the hour to get the first pass as 18:13 and the second as 19:48.
The 18:13 pass is the one to look out for. Hope that helps:)

ok, so the 04:42 PM from the Nasa site is not shown on the other 2 sites (because it would be too bright?).

I do know the UTC/UTC+1 conversion, that is why I said that the 2 other sites matched.

Who is hoping for frost tonight?

kierank01

I think I saw it .

It appeared way to the west, and within about 3 minutes it went almost fully overhead, and disappeared in the east, but a good bit above the horizon.

Hal1

Saw it too. Great night for viewing with the Moon and Jupiter.

UTC=GMT. UTC+1 =GMT+1.
Many people felt it uncomfortable that Grenwich Mean Time or British Summer Time was the International standard and it 'seemed'like the EMPIRE was even claiming that the beginning&end of time began in the UK.
for all intents&purposes they are exactly the same thing except a UNIVERSAL way of saying it.

NASA also use Central standard time{CST}and Central Daylight Time{CDT}which means you have to subtract 6 hours from UTC and UTC+1.

another thing to remember is the USA does not Spring forward or Fall{Autumn}back at the same time as Ireland and the UK,it has varied from two weeks to a month!

Good news is the NASA homepage is now testing a Beta version to show each Country times in its own time-zone!
Glad to have made that as clear as mud!:)

Bee-you-tifull view of the ISS here in the west about 45 minutes ago-first time in ages I managed to see it.

Hi all, might get a chance to get out to brittas bay tomorrow evening, a bit clueless using the sites listed, does anyone know if there will be any passes in that area tomorrow and the times?

Thanks!

Tomorrow:

Date: Sunday, January 24, 2010
Time: 05:37 PM
Duration: Less than 1 minute
Maximum Elevation: 12°
Approach: 12° above SSW
Departure: 10° above S

You should be in a good spot with it being so far down the horizon.

NoQuarter

Thanks Hal1, which site do you use for that info? I dont want to keep asking everytime!

This, http://spaceflight.nasa.gov/realdata/sightings/cities/view.cgi?country=Ireland&region=None&city=Dublin&ss=201001240537ISS there were 2 listings for the ISS tomorrow 5:36pm is probably the better time its less than a minute of viewing also.

Appears 17h31m21s 1.8mag az:276.2° W horizon
Culmination 17h35m36s -0.1mag az:215.3° SW h:14.2°
Disappears 17h39m49s -0.4mag az:154.0° SSE horizon

might be tough to spot, but it passes very close to jupiter which should be visible before the pass

calchas

there is a short explanation of how to use the sites on the ias website.
www.irishastrosoc.org

If you can't follow it, let me know and I'll make improvements
