The observing team at Gemini keeps a detailed log of each night's science observing, also noting weather issues, technical faults and any time spent in planned engineering. It is read by Gemini staff early each morning. A summary of the night is written at the end of observing and included at the top of each night log. That summary is posted here, unedited, to give interested users a feel for what we're doing.
