Fall?

Three days past the equinox into "official Fall" and the extended forecast doesn't show any lows below 73F.  OTOH, none of the predicted highs get above 90F, so I guess that sort of counts.  Anyway, the days are noticeably shorter, so this hot streak can't keep on much longer.

FWIW, today's APOD has a summary of this fall's astronomical highlights.
