                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 CU01 did a time trade with JH02, hence the CU01 entry in the schedule.
 I think it was internal between the observers or payback time.
 We sprung forward this morning and the PU02 time is correct at 4.8 hrs.
 We opened up around 22:15.
