              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started out clear and calm. Everything was great until it wasn't.  Starting at 20:40 we faced problems with the altitude axis that eventually defeated us.  Problem report has been sent, hopefully daystaff will have better luck than we did.
