ISS viewing opportunities

[Rick]

I walked outside after last night's committee meeting, looked up, and saw ISS going overhead. It turns out there are some fairly reasonable passes this week. Note, add an hour for BST times...

Over the next few days it's in almost constant illumination, so it's a great time to catch a sight of it:

So, what time would the information below be in ENGLISH! if it was flying above us?

PS..................My head starts hurting severely when people ask me to convert BST, UTC, TUC & GMT.
Sorry don't know where TUC came from as my head hurts.

[mickw]

21:31:14

10:31 and a bit

And yes, I am guessing 

[PhilB]

Go to http://heavens-above.com/ and set up an account. This site gives local times for your declared location and includes adjustment for daylight saving.

[Tony G]

Phil,

I have already got this set for my home location, and remember at one DSC 'Mark the Magnificent' was going to show us how he images the ISS, so I phoned 'she who must be obeyed' and asked her if she could look up fly-by's for that evening which she did.
We waited...................and waited....................and waited.................and then realised about the +1 daylight saving, or whatever the bloody time difference thingy is, and we had the wrong time.
But we did manage to catch a glimpse a little while later as it passes over every 90 minutes approx.

Tony G

PS..............................

And yes, I am guessing 

That's unlike you.

The headings above the columns tell you.

Date is (20)YYMMDD so that's 25th June 2010 in this case.

Time ISS rises is 21:31:14 UTC which is 14 seconds after 22:31 BST, but that's assuming a nautical horizon, so chances are you won't see it for a minute or so after that. You want to be looking towards the sout west (bearing 222 degrees from true north).

ISS is at its highest elevation at 21:35:53 UTC, at which point it'llbe on a bearing of 149 degrees, and it'll be 26 degrees above the horizon (so probably not the best of opportunities).

By 21:40:39 UTC it will have vanished somewhere off just north of east.

If any of the times had an asterisk after them then the station would not be illuminated by the Sun, so wouldn't be visible.

If instead they had an 'o' after them then the Sun would still be above the horizon...

to convert BST, UTC, TUC & GMT.
Sorry don't know where TUC came from as my head hurts.

UTC is Real Time. GMT is the old name for (almost) the same thing. BST is an abberation dreamed up by Franklin, Willet, and the rest.

[mickw]

Time ISS rises is 21:31:14 UTC which is 14 seconds after 22:31 BST

I guessed right 

[PhilB]

Yup, daylight saving can be a bit of an issue, Tony. Trouble is the only thing that these websites really seem to have in common is that their timing estimates don't clearly indicate whether daylight saving is being allowed for or not 

[The Thing]

... don't clearly indicate whether daylight saving is being allowed for or not

But the table clearly says UTC on the second line...

[Mike]

I hate BST. It isn't relevant in this day and age and should be scrapped.

[mickw]

says UTC on the second line

That's Time Zone not "time"

I hate BST. It isn't relevant in this day and age and should be scrapped

But what about the poor farmers and the war effort 

[The Thing]

Time Zone is displayed as UTC +0:00. If it was BST surely it would says UTC +1:00 (since GMT = UTC for practical purposes). This is what Heavens Above shows.

[Tony G]

 

My head is now thumping. I think I now have an aneurysm. (i fink that's how you spell it)

Can someone just PM me 10 mins before it comes over.

Tony G

PS...................As we are still talking about the ISS, does that mean that this thread hasn't been hi-jacked yet?

Unlike me, Duncan, you're not wrong 

[PhilB]

You'll have the forum police after you, Tony. If we all do this the effect could be similar to a denial of service attack on what ever controls our PM service   

[mickw]

Perhaps if I read posts properly, I might get it right 

Note times are given iin UTC, not BST.

Rick

Me (after not reading the above  )

Duncan - correct 

Observer's location:   Dulwich, 51.4350°N, 0.0650°W

Apologies to everyone anyone that believed me 

I'm going to have some beer now - lots of beer

[PhilB]

Managed to catch the 22:57 pass last night. Something to look at in an otherwise 'orrible sky.
