: International Space Station and strange trail

On 26 Feb 2012 I took a 5.7 second exposure of the ISS over The Southern UK at 18:34 hours GMT. The Moon, Venus and Jupiter are prominent with the ISS white trail on the top right. Just above the moon though is another trail at appx. 45 degrees to the ISS trail. This consists of 5 instances of about 5 spots of light (one spot is a slightly red color). I can't think what type of Satellite could result in this strange occurrence!.... Twilight Zone?

Thanks Chanda, (I hope I haven't posted this twice.. in quick reply?) Anyway I was lucky that the three 'big shots' of the night sky were all huddled together AND the ISS passed close. It helps having a website that predicts the time and also a free Astronomy software program called Stellarium. This enabled me to get the camera set up ready as the ISS whizzed past!

I love Stellarium. That could be another satellite above the moon. I saw a tumbler out in my observatory once that was cool, bright to dark all the way across the sky.:rolleyes:

I have converted the picture to a negative and zoomed in with increased contrast. I have drawn a rectangle around each instance of the light pattern.
As the camera shutter was locked open for nearly 6 seconds, why is there no blurring? Even if it was an aircraft, surely the four points of light should be 4 'short lines' as the lights were blinked on and off. If it were a Satellite it would be a continuous trail like the ISS one. Strange!
