              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Humidity was fine tonight, but the Optidew sensor was still reading high, and as a result the dust counters weren't running.  I used the handheld counter a few times and it was reading very low, despite some haze down in the basin.  I hope it's working correctly.
A user error made it necessary to retake cals, and the first half observer ended up with not quite enough time left for one more target, so handed over early to the onsite class.  I changed the end and start times to reflect this change.
