Off topic, but if you're up, don't forget the step outside tonight to see the Solstice Lunar Eclipse. It's the first solstice eclipse in 456 years, and will be the only one that happens in our life times.
Per Nasa: The eclipse begins on Tuesday morning, Dec. 21st, at 1:33 am EST (Monday, Dec. 20th, at 10:33 pm PST). At that time, Earth's shadow will appear as a dark-red bite at the edge of the lunar disk. It takes about an hour for the "bite" to expand and swallow the entire Moon. Totality commences at 02:41 am EST (11:41 pm PST) and lasts for 72 minutes.
Just remember to dress warm!
