              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Weather first half had patchy clouds with tantalizing holes, but there was rain and lightning quite nearby.  I took a chance and opened for a short while, remaining up in the dome to monitor weather directly.  We got the minimum required data for TripleSpec checkout, but the clouds quickly got more cantankerous.  Second half the radar gradually receded but the clouds just got worse, and we never reopened.
We checked out TripleSpec!  Off sky and on sky!  It works, and it's in focus, and we think it's about the same sensitivity, although it was hard to be certain while struggling with clouds.  So hopefully it can appear in more night logs to come.
