              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The afternoon thunderstorms dried out more effectively than previous nights, and we were able to open shortly before midnight.  Unfortunately the echelle ICC crashed just as we got on sky (perhaps triggered by a stuck motor, this will be investigated), so the first half observers weren't able to get even one spectrum.  The second half observers had better conditions, with mostly clear skies and good seeing.  Humidity started to rise after 3 am and by 04:30 was high enough to require closing.  It dropped not too long after that but it was too late for the observers to get more targets, so we stayed closed.
