                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Camron Hastings
    We opened late after a big thunderstorm at about 19:45 MDT. Just
barely in time for flats, but squeezed them in!
    Right after getting the flats in we had time for focus and had to
close again at 21:03 MDT due to rising humidity and more rain clouds
approaching.
    We were able to open again at 00:05 MDT in hopes that the clouds had
left us alone for the night. When I switched over to second half the
clouds returned but we soon simply tried to shoot through the cirrus that
remained. Near the end of the night it cleared.
