Activies fitting for the day:
Because of the association with flames and fire this is a good night for candle scrying as well as for making your own ritual candles (or just blessing the ones you buy from the store).
Clean your house physically or spiritually. Clean out a closet or even just tidy your junk drawer. Bless salted water and spurge the rooms, go around the home with incense letting the smoke enter into each corner.
Light a candle and utter a prayer rededicating yourself to the Gods.
Consider leaving a strip of cloth or a ribbon outdoors overnight for the Lady to bless.
Take a walk and look for any changes in the hold winter has on the earth.
