              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend,J.Dembicky
At the start of the night it was very cloudy, with a few storm systems in the basin that we kept our eyes on.
Seeing and cloud conditions were not good enough for APOLLO to range to the moon.
At about midnight, the clouds cleared up a little bit and with no nearby threat of rain we opened the dome--only for the dust to spike, so we closed back up immediately. We think it was pollen, from shaking the trees. The dust counts stayed too high for the rest of the night.
Engineering:
- Reset all four drive controllers
- Restarted TCC and hub
- Had issues with tertiary position after this
- Zeroed NA2 and Agile rotators
- New DIS slitviewer masks
- New echelle slitviewer mask
- Tracking oscillation tests with the dome closed due to high dust counts
