<p><strong><font size="3">September 19, 08:50pm looking south east , a star or something is getting brighter and bigger in a 5 seconds time zone and then just dims out to nothing.&nbsp; Compared to jupiter which was on the right, (to the west off) this star got 3 times bigger and 5 times brighter. Never before in all of my years of watching the sky have I ever seen something like this with the naked eye.&nbsp; Can anyone explain this ?</font></strong></p><p><strong><font size="3">(only had one beer that night <img src="http://sitelife.space.com/ver1.0/content/scripts/tinymce/plugins/emotions/images/smiley-wink.gif" border="0" alt="Wink" title="Wink" />)</font></strong></p><p><strong><font size="3">Dscorpionking</font></strong></p><p><strong></strong></p>

My location is 42" 51.25' N latitude and 80" 48.317'w longitude.&nbsp; According to starry night, Iridium 70 or 74s passed by at that time so you know you stuff ! I love learning about this infinite world of ours and the more I learn the more i want to know.&nbsp; </p><p>Thanks so much, <img src="http://sitelife.space.com/ver1.0/content/scripts/tinymce/plugins/emotions/images/smiley-cool.gif" border="0" alt="Cool" title="Cool" /></p><p>Dscorpionking</p><p>&nbsp;</p>

Azimuth Distance toflare centreIntensity atflare centre(Mag.)Satellite18 Sep20:53:21-256&deg;122&deg; (ESE)21.0 km (W)-8Iridium 6719 Sep05:45:02-153&deg;203&deg; (SSW)31.8 km (E)-8Iridium 5619 Sep20:47:20-655&deg;123&deg; (ESE)6.1 km (E)-8Iridium 72So you saw Iridium 72, with a magnitude of -6 (that's brighter than even Venus ever gets) in the ESE at about 8:47:20I should point out that if you are going to look for Iridiums, it is essential that you have a very accurate timepiece. They only last from 10 to 30 seconds, so if your watch is off by a minute, you can easily miss it.I see you have another one in the same general area at 8:20 tonight and 8:14 tomorrow. (both are a little further to the south)You also have a pretty good pass of the ISS tonight at ~ 7:30 with the ISS passing below the north star. <br />Posted by MeteorWayne</DIV></p><p>Thanks again MeteorWayne.&nbsp; Yes, I was able to see quite a few more iridum flares satellites, but I was&nbsp; not able to see ISS till tonight.&nbsp; At 20:15:57, I was surprised to see how bright it was going across the NM to ENE sky.&nbsp; Thanks for the link of heavens above, so now I know that it is not a satellite going by.&nbsp; With the moon set on the western sky, it was just a perfect night to gaze the stars .&nbsp; </p><p>Thanks again, </p><p>Dscorpionking</p>
