  1. Regular startup procedures
    1. North mirror door not opening with command; East and West also struggled because of this
    2. Tried closing and reopening them twice, north worked on second try
    3. BUT East decided to stop opening halfway
    4. Closed and reopened and then heard a bang followed by harmonic clanging
    5. East mirror door had fallen down back over the mirror
    6. Clevis pin has disappeared
    7. Checked mirror; No visible damage and pin does not appear to be there
    8. Replaced Clevis pin
    9. SUCCESS; All doors open
  2. Finished startup procedures
  3. Followed Ian/Dr. Meyer's observing plan with their oversight
  4. Attempted flats with new string lights
    1. No glare but indeed too dim
    2. Used regular in-dome lights and the yellow LED lamp to boost flux
  5. Closing procedures in dome to prep for darks
    1. North mirror door didn't budge
      1. Helped it along by hand, success
    2. Took darks
  6. Closed up the control room
