With last night's problems being remedied by the day crew both on the
mountain and downtown (thanks guys), the program moved back to
spectropolarimetry now that objects could again be placed in narrow
slits. As can be seen in the satellite image, tonight was a race
to do as many targets as possible before the advance cirrus clouds of
a powerful Pacific storm system reached Mt. Bigelow.
Observations were not seriously affected by clouds until the very last hour
of the night. Seeing varied between 1.2 and 2 arcsec, with most of the good
seeing occurring during the second half of the night.
Tomorrow night promises to be a cloudy affair with possibly some
rain showers late.
