Observing Summary:

We took spectra of photometrically variable stars in the Cygnus OB2 Association.  All of the problems of the previous night have been fixed.  It should be noted that there remains the lingering problem of declination oscillations in the guide camera, a condition which improves at lower airmasses but persists nonetheless.
