    Saturday was "Sun Fast Day"
    From: Frank Reed

    This past Saturday evening at 8pm EDT or early Sunday morning (0h UT) the the Sun was directly over longitude 184°6'34" W while its latitude was near 15° S. This was "Sun Fast Day" for the year. Since it was midnight UT, the Sun "should" have been at exactly 180° longitude. Instead it was ahead of itself or "fast" by 4°6'34" or equivalently the Equation of Time was 16:26 (16 minutes 26 seconds) fast. Combine this with the time change less than 12 hours later, and the Sun was just wacky this weekend. It's straight downhill from here. The Sun gets sleepy through winter, and by February 11 or so it will be slow by 14:13, its slowest for the year. That's a thirty minute flip in less than a hundred days or just about twenty seconds every day. What a rotten clock. We gotta fix the Sun!
