Narrative:

I was on an ILS approach to runway 15 in det. ATIS called the WX 200' and 1 mi visibility. I shot the approach and landed and then realized the minimums for this approach are 250' and 1 mi. There were no problems, close calls or anything said by the controllers. 7 other airplanes landed behind me. I was in an small transport.
