Red big circle at the sky, may be at the half size of the full moon!Tonight, we had been just get out of our class around 10 pm and we were walking towards the car that I just started watching the sky as I usually do at nights. First the moon caught my attention, but few seconds later I was astonished by noticing a red-brown circle almost at the upper side of Orion constellation. It was very big in comparison to the usual size of the planets like Jupitor or Venus as one can see with naked eyes! I checked with my friend and she was also very surprised by that. Actually, it was like a very big planet, I were not familiar with astronomy I would have said it was a planet passing by, but fortunately I know enough that none of the planets could be seen at this size with naked eye. Anyhow, I did not noticed any motion, and after few minutes it can not be seen any more. Anybody may know what it could have been!?
