              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
At 20:19, I switched instruments from Tspec to Echelle, and after the tcc
set inst command, the secondary got lost. Luckily, Russet was on, and
helped me recover pretty quickly. We only lost 10 minutes of sky time. See
PR 1489 for details.
We pushed through clouds during the first half, but remained open all
night. No other problems.
