Observing Summary:

Spectra taken of 5 candidate galaxy cluster members plus
appropriate calibration.

There were a few very small patches of clouds to
the northwest and haze at sunset but otherwise
clear. Night may have beegun photometric.
However, some periods of dramatic drops in the
guide star flux, probably due to thin layers
of clouds and some clouds at sunrise to the east
suggest the night was not photometric.

Variable seeing when pointing into the wind.
