Narrative:

I was on an IFR flight plan to ump and in contact with ATC at the time of the incident. Descending through 3;200 MSL; heading 180 degrees and around 4 miles northeast from ump; a disc shaped object approx. 16 inches to 2 feet across passed within 100 feet of my right wing tip and was at or very close to my altitude. The object passed very quickly; but I had time to point it out to my wife (acting as co-pilot at the time. She holds a private pilot certificate and is IFR rated and current. Approx. 1;000 hours as pilot in command). It was the opinion of both of us that the object must be a drone and not a balloon or kite. I advised ATC of the incident.
