On a clear sunny day, cylindrical metal grey object seen. No markings, shaped like capsule observed for about 15 seconds

About 1:30 PM in the afternoon on a bright, sunny, clear day. From my window I saw one dull metallic grey object having no markings of any kind hovering in the sky to the North West of the city. Unable to accurately describe size as I do not know how far away it was. Judging only by it's clarity I guessed it to be less than half mile distant at about one thousand feet altitude. Size at a guess about 30 feet in length and approximately 8 feet in width. It was floating horizontally, stationary at first for about 10 seconds then slowly moved South East out of my view. It was cylindrical with rounded ends, the same shape as a medicinal gelatin capsule. I am  a licensed pilot (fixed wing)and a retired police sergeant. I would estimate my observational ability as very good.
Witness indicates that the date of the incident is approximate.  PD
