                ------------- ACTIVITY LOG --------------
Observing Specialist: Russet McMillan
Clouds in the vicinity thickened after sunset; we focused but didn't
manage any science.  Near midnight the clouds thinned and we
re-opened, but it wasn't really clear until around 01:30.  Seeing was
greater than 1.5, sometimes greater than 2 arcseconds.
Telescope and SPIcam worked well.
