Condensation on Skylight After Insulating...Is This OK

I just insulated the skylight that is in my cold attic with 1 1/2" of a foam square, foiled on both sides. I thought I had a good tight fit until I took down the foam block today and noticed some condensation on the lower part of the skylight , about 10% of surface area of the glass). It had onlly been up there for 24 hrs. Is this to be expected or is there something else I need to do to resolve this? Thanks
