High humidity at the beginning of the night kept us from opening

Observed with Echelle for about 3.5 hours, then switched to
Retrocam to attempt extremely-high-frame-rate photometry of
close-passing asteroid 2007TU24. Observed for about 2.5 hours
and obtained 520 images at up to 4 per minute (5 s exposures).
Reduction will be interesting.
