semi-transparent big wheel like object. spinning in a stationery position for about 10 miutesspinning at about 1 revolution every 5 seconds, but a very large object so it seemed to be be spinning very fast.A perfect circle, but could only be seen when there were clouds present, the object appeared to be mostly transparent, mostly the rim could be seen against the clouds.The object did not move from its fixed possition, as the clouds dissapeared so did the object.The sky was very dark, the object was huge, none of us had ever seen anything like it.We wonderred if it could have been a light projected onto the clouds from earth, but could not see anything that might be creating this.We took 4 pictures with a digital camera but all we got was complete blackness.
