              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk,R.McMillan
Weather was not ideal, but we opened at 22:20, and used bright stars to adjust the DIS slitviewer focus. We attempted Shack-Hartman, then moved to echelle pointing and sag coefs. A storm formed to the south of us, and we closed around 03:45.  Thunderstorms hit us at 4:15.  We did not open again.
