Dec afternoon sitting in hot tub on a clear afternoon. Absolutely nothing in the sky & peaceful & extremely quiet. Looking up at sky to the west I saw a very large totally solid black object that moved from one side of the sky to the other in a perfect straight line. There were no lights on it & no jetstream, no sound. I've never seen anything like that in my life. However, I didn't have my phone with me or i could have videotaped it as it was so clear - not a cloud in the sky. And so quiet. A little eerie in fact. Ran into the house but it was gone by the time I reached my phone. So I drew it while it was fresh in my memory. I got on line to look at unusual objects in sky, what balloons look like, got onto Mufon site but nothing like what I witnessed. Still puzzles me. So curious to see if anyone else saw the same thing or perhaps tell me what I saw..
