Night Assistant:

Also Present: 
A. Kunder, David Rojas
Problems: 

-  Unable to login with proposal ID

-  SISPI issues around 10 am

- Brief interlock error around 4 am

Comments: 

- The first is self-explanatory: I couldn't log in with the credentials I was instructed to use; had to use someone else's information

- Second: the seeing got very bad at some point in the night (>5") and guiding shut off. They stopped responding, and we had to reboot SISPI several times. Apparently, this was a LabView error...

- Brief interlock error which was resolved by pressing "configure"

Comment: 
Seeing never went below 2" for more than 10 minutes at a time, and so no data suitable for weak lensing analysis was collected.
