Coming out of my office for a breath of fresh early morning air before giving my nightshift report and going home I observed a stainless steel looking perfectly round sphere stationary in the sky about 2-3 miles south east from my position and about 3000 feet in the sky which would place it's position over the east end of Sky Harbour Airport. The time was about 5:30 or 5:45 AM and the sun had not fully risen but the sky was full of light but the globe itself was reflecting bright sunlight. the sphere/globe reflected a gray/silver color just like stainless steel and there were no other features about it. It was just a perfectly round globe devoid of any markings or external material. If one holds a large childs marble at arms length you get the idea of what size I was seeing. This object was perfectly stationary in the sky and clearly visible to anyone who would look up and as I said looked for all the world to be made of stainless steel. I watched it for a short while and first thought it was a TV satalite. I went back into my office, gave report for my shift and went home not thinking anymore about it. A few weeks later coming out of my office for a breath of fresh morning air at the same time as before i saw it again in the same position perfectly stationary in the sky with the early morning sun reflecting off its exterior. I watched it again for a little while wondering just what it was then gave my night shift report and went home. Before I drove off the parking lot I took another look but could not see it again. On the way home I began to realize that it could not be a TV satalite because it had no array of antenas or solar panals etc. and it was positioned in the atmosphere only a few thousand feet up. I am a retired RN and have never seen any other odd objects in the sky.
