Keep in mind thin wispy clouds at much higher altitudes reflect very little light from the ground thus making them much harder to see.<br /> <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

He claimed it to be stationary... wouldn't that preclude it from being an iridium flare? <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

no luck, there was a flare about an hour after wahtever it was i saw.&nbsp; thanks for the link, though.&nbsp; <br />

 

[ktfite]

it was about 45 degrees up from the horizon, in the nne <br />

<p>Thanks for the clarification, <br /><br />I have a habit of keeping an eye on clear night sky, I even have binoculars at hand always on a clear night to catch a satellite or two.

From 45 degrees and up, the spot is indeed quite small, but ones lower on the horison, while not as bright due to passing through more air and a greater distance, can last quite a bit lomger since the spot is spread into a larger ellipse as it intersects the earth at an angle.</p><p>With binoculars, you can see Iridiums for quite a while before and after the Flare as well.</p><p>It is also often useful to look at that same spot about 10 minutes before and after with binoculars. You can often see the leading and trailing Iridiums, that don't get as bright.</p><p><br /><br />&nbsp;</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

I believe you. But I do not believe supernova because it is creation of space mirror. <font face="Times New Roman" size="3"><span style="font-size:10pt">From the ancestral time the world space research established on blind theory. We although demand that we have discovered lots of mysteries viz. milk ways, galaxies, nebulas, white drafts, black holes etcs., in real they are creation of space mirror. SPACE MIRROR is the truth and hidden mystery of the space.
