              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
NM04 finished early and handed instrument over to next observer.  We fought clouds all night.
The old weather sensor dewpoint seems to be frozen and reporting inaccurate humidity/dewpoings all night.  I use the optidew and SDSS sensors.
Closed at 00:39 due to humidity.
re-opened at 02:00.  Humidity rose again right at the end of the night but I let Patrick finish his final exposure since there was not a rain threat nearby.
No Echelle IOL since the I didn't get a chance to take it as the start and Patrick was using the Echelle for cals at the end of the night.
