In just under 10 minutes, then again at 22.53

Yes it will be arriving in North Devon at about 21:20 and be over London at 21:21.
Right kids! For all those who haven't gone out looking for an iridium flare, tonight is a good a night as any to start!

Enter your town and find your town. Click Iridium Flares > Next 24 hours. This will be different from town to town, but here is the first result for my town:
11 Aug 00:06:17 -7 36° 242° (WSW) 6.3 km (E) -8 Iridium 72
Now the date and time are obvious, this third column is a column indicating magnitude. This is a measure of the brightness of a celestial object. The lower the value, the brighter the object, so magnitude -4 is brighter than magnitude 0, which is in turn brighter than magnitude +4. The scale is logarithmic, and a difference of 5 magnitudes means a brightness difference of exactly 100 times. A difference of one magnitude corresponds to a brightness difference of around 2.51 (the fifth root of 100). A magnitude of -7 is exceptionally bright for an iridium flare so I'll definitely be out watching this one tonight!
The third column is the altitude in the celestial sphere. http://www.heavens-above.com/images/azel.gif This diagram shows you what the altitude is, basically the horizon is 0 degrees and directly above you is 90 degrees. As you can see, my iridium flare is at 36 degrees, which means it will be 36 degrees above the horizon. The fourth column is the Azimuth, this is the direction of a celestial object, measured clockwise around the observer's horizon from north. So an object due north has an azimuth of 0°, one due east 90°, south 180° and west 270°. Azimuth and altitude are usually used together to give the direction of an object in the topocentric coordinate system. My Azimuth is 242 degrees, which roughly equates to West South West.
The distance to flare centre and Intensity is not something you need to confuse yourself with, so if you want to skip this paragraph. Basically it is the distance to where the best view of the flare will be, because it will be it's brightest at this point. If I travel 6.3km to the East, I will see the flare at its brightest -8 (the brightest you can actually get an Iridium Flare).
The last column is the name of the individual satellite that you will be seeing.
Iridium Flare Viewing Tips

Very good sighting tonight and it seemed to stay visible for longer as it moved away towards the east.

It was visible almost right down to the eastern horizon.

Of course

That's the link for your hometown! Nothing till 3am for you i'm afraid!

I can't stay awake till then any meteors?
Hmm, the ISS was moving too quickly for me and my bins tonight. 
Next purchase - a tripod!
I'm off to find the milky way.

Missed that one............
Have to try for the 22.53............clear skies over london.
By 'clear skies' I mean no cloud............the regular visibility on a clear night in central london is so bad that the only things I can see looking south, sw, west are Jupiter and Arcturus..........
The light pollution blots out everything else............
Sometimes on a winter's night I can see a lot more....

Here is the path it will take. See Track over ground
Thanks henry............that looks a bit different to the last few nights, when it's gone right over my roof, so I could only see it halfway across the sky before it disappeared above me.
Looks like i should see it all the way across tonight........

No it will disappear early on. The dotted part of the track is in the earth shadow.
I wont see anything here, its been raining nearly all day for a change and there is thick cloud. 
oh and it's freezing

Oh well, that'll be quite good if it just disappears mid-air rather than disappearing because of a building.........
Where is Jupiter tonight? Either I'm being tres thick, or it isn't out.
I never realised how many stars where in the sky. I've chucked away the starchart I have - it's pants!
Next ISS pass - 22.53
