OK! Today was the earliest sunset of the year, for our latitude. So now we can start gaining light in the evening.
This is not to be confused with the winter solstice (21Dec12), which has the shortest total daylight of the year, and just happens to coincide with The End Of The World! a.k.a. the new year of the Mayan calendar. Coincidence? Not really, as the Mayan calendar is astronomically based, and the winter solstice marks the beginning of their calendar year, and this year the date rolls from 12.19.19.17.19 to 13.0.0.0.0 Despite using a base 20 number system, at least the new year's day on the Mayan calendar makes more sense than the cobbled together European based calendars (Julian & Gregorian).
Oh, and for our latitude, we have to wait until our new year's day to get past the latest sunrise.
Alright, it has been snowing here. Apparently only once about every decade is there a white Christmas in this part of Germany. If the current trend holds, this will be that year. And to tie this back to astronomical events: The sun is at such a low angle (currently <18.5 degrees above horizon at solar noon) and above the horizon for such a short time (currently 8hrs:22min), it doesn't seem like it will melt too soon. ...and since I spend a few days this past summer making the calculations, I can tell you that the current daily clear sky solar energy delivered to a 1sq.meter horizontal surface is 1.4kWh (...or about the same heat energy released as one hour of the big burner on the stove top set to medium-high, ...but distributed over 10sq.ft), and this energy is only 1/6 of the summer solstice amount. However it is cloudy every day, and the snow reflects most of that energy, we aren't even getting much solar heating to melt our snow.
OK. In a practical terms this means, the snow and ice are piling up but not melting, and this makes for a difficult commute by bike. Consequently I am using the train much more frequently than normally. And so is Betsy; she bought a month pass. Thank goodness for the trains when the weather is not fit for biking --and that is saying something, when it comes from me.
