                   ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 We had a very special guest stop by the observatory tonight and pay us a
 visit, Tia Hoyes (former 3.5m operator).
 I filled the echelle tonight and went up to watch it fill just before
 18:00.  The shield side took considerably longer (2-3 mins) than the CCD
 side.  I don't know if this is normal but thought I should not it.  Tank
 pressure was around 6PSI during the fill.
 The humidity rose above closure limits as the sun set.  We had partially
 cloudy skies to our N and clear to our SW.  The skies did clear but the
 humidity never dropped below closure levels all night long (with some fog
 forming around midnight and lasting a hour or so).
