Narrative:

Found 3 mi hold in overcast/broken deck. Performed aerobatics above WX. Upon descent back through the hole, found I was 15 mi north of the airfield. Sunset was XX00 pm, due to being further north than I had planned, I landed 4 mins after sunset. My aircraft has no exterior lights. Lesson learned -- be aware of winds aloft, don't push WX.
