Observer Support:

Night Assistant: 
Leonardo Paredes
Also Present: 
David James, Steve Kent, Richard Kron, Ann Elliot
Problems: 

A Interlock error associated with the shutter occured during exposure 228989 at 5:34 p.m., which was an I-band flat field.  We tried reset, configure, restarting SISPI, restarting the role, and cycling power to shutter, but this did not correct the error.  Alberto Alvarez reset the shutter again from the controller, and this corrected the problem.
