Witness Account

Odessa Texas. 3 days ago I saw a round object I thought might be a balloon. It was big and round. Looked silver. It was traveling east. No sound. And several miles away I assume. When I spotted it, it started to get lighter in color and then disappeared, in about 10 seconds. I had asked my husband"what is that" as I pointed at it. By the time he turned to look it had disappeared. We continued looking and within 10-15 seconds it reappeared traveling west this time and only lasted several seconds before disappearing again.
