                ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: G.Saurage
 Thick fog, some rain, constant high humidity all of 1st half.
 2nd half Observing Specialist: R.McMillan
 Second verse, same as the first.  The secondary temperature sensors
 are still reporting anomalous values, but it's most likely a
 measurement problem rather than a heat source warming the mirror.
