Hello Stemians. I like to share this video that I published in my Sangstar1 channel in YouTube on Apr 4, 2011.
I very much welcome your comments regarding this object which has five circles.
The official view of the Astronomical society in Melbourne Victoria, is that is a contrail.
Contrails are vapours which are created by aircraft engine.
However if this is a contrail how is it that its descending? It has five circles and descending in a straight line.
Contrail vapours do not descend in a straight line downwards, contrails merely float in the air like clouds on a breeze.
