                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 We were open long enough to take some twilight flats but before we
 finished the skies became overcast and we were forced to close again.
 We did not open again because of various weather related problems.
 I spent time tonight collecting irradiance data on the secondary
 truss calibration lamps.
