Saucer shaped object

This info was from my father, who recently passed away.  He was in Nashua by Dunkin Donuts on Canal St and when he came outside he noticed a number of people staring at the sky.  He told me there was no sound and the object was several hunderd feet above the ground.  He said there was one red light on the botton and what appeared to be a row of rotating windows with a very bright white light.  He said there were several witnesses, although there was nothing in the papers.  About 6 months later, maybe even 1.5 yrs later he was xmas shopping at the mall of NH in manchester and when he came out of Lechemere's he looked up and the same craft was hovering just above the trees maybee 200 feet up.
Source of report indicates that the date of the incident is approximate.  PD
