Even though climatological winter has already begun as of December 1, today marks the start of astronomical winter based on the earth’s position relative to the sun. You can watch an interesting video about this year’s winter solstice at EarthSky at https://www.youtube.com/watch?v=pTy2oDxGAuM. From here on, the days begin to get longer again and the sun will get a little higher in the sky every day from now until the summer solstice in June, although the changes will occur very slowly for the next month before they start to speed up as we approach the spring equinox.
