huge disk/saucer with blinking lights

huge craft - still very light/bright outside....some clouds but mostly very clear out.  HUGE disk craft with blinking lights moving slowly.  so large I thought must be right above trees but when compared to trees and clouds ....very high up....appeared to have windows or what looked like windows to me.....rotating with many blinking lights. was not covered by cloud coverage - there was still alot of light in sky and was very very visible and not obscured by anything.
