                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Clear and photometric all first half.  Temperatures were sufficiently
warm tonight versus last night such that no equipment oddities were noted;
DIS was calibrated just fine on the first attempt.
 2nd Half Observing Specialist: R.McMillan
 Second half remained photometric, with seeing around an arcsecond.
 Everything worked well; the blue-side bias level is still lower than
 normal, similar to last night's.
